1969–1971: Black Sabbath and Paranoid

The band's first show as Black Sabbath took place on 30 August 1969 in Workington, England. They were signed to Philips Records in November 1969. They recorded their first single, " Evil Woman " (a cover of a song by the band Crow), at Trident Studios. "Evil Woman" was released on 9 January 1970 through Philips subsidiary Fontana Records. Later releases were handled by Philips' newly formed progressive rock label, Vertigo Records. "Evil Woman" failed to chart.

The band were afforded two days of studio time in November 1969 to record their debut album with producer Rodger Bain. Iommi recalls recording live: "We thought, 'We have two days to do it, and one of the days is mixing.' So we played live. Ozzy was singing at the same time; we just put him in a separate booth and off we went. We never had a second run of most of the stuff".

On 11 November 1969 Black Sabbath recorded a 4-song session for John Peel 's Top Gear radio show. The four songs were " Black Sabbath ", " N.I.B. ", "Behind the Wall of Sleep" and "Sleeping Village". Broadcast on 29 November 1969, this gave them their first exposure to a UK wide audience.

Their eponymous debut album Black Sabbath was released on Friday the 13th, February 1970, and reached number eight in the UK Albums Chart. Following its U.S. and Canadian release in May 1970 by Warner Bros. Records, the album reached number 23 on the Billboard 200, where it remained for over a year. The album was given negative reviews by many critics. Lester Bangs dismissed it in a Rolling Stone review as "discordant jams with bass and guitar reeling like velocitised speedfreaks all over each other's musical perimeters, yet never quite finding synch". It sold in substantial numbers despite being panned, giving the band their first mainstream exposure. It has since been certified Platinum in both U.S. by the Recording Industry Association of America (RIAA) and in the UK by British Phonographic Industry (BPI), and is now generally accepted as the first heavy metal album.

The band returned to the studio in June 1970, just four months after Black Sabbath was released. The new album was initially set to be named War Pigs after the song " War Pigs ", which was critical of the Vietnam War; however, Warner changed the title of the album to Paranoid. The album's lead single, " Paranoid ", was written in the studio at the last minute. Ward explains: "We didn't have enough songs for the album, and Tony just played the guitar lick and that was it. It took twenty, twenty-five minutes from top to bottom." The single was released in September 1970 and reached number four on the UK Singles Chart, remaining Black Sabbath's only top 10 hit. The album followed in the UK in October 1970, where, pushed by the success of the "Paranoid" single, it reached number one on the UK Albums Chart.

The U.S. release was held off until January 1971, as the Black Sabbath album was still on the chart at the time of Paranoid ' s UK release. The album reached No. 12 in the U.S. in March 1971, and would go on to sell four million copies in the U.S. with virtually no radio airplay. Like Black Sabbath, the album was panned by rock critics of the era, but modern-day reviewers such as AllMusic's Steve Huey cite Paranoid as "one of the greatest and most influential heavy metal albums of all time", which "defined the sound and style of heavy metal more than any other record in rock history". The album was ranked at number 131 on Rolling Stone magazine's list of The 500 Greatest Albums of All Time. Paranoid ' s chart success allowed the band to tour the U.S. for the first time – their first U.S. show was at a club called Ungano's at 210 West 70th Street in New York City – and spawned the release of the album's second single, " Iron Man ". Although the single failed to reach the top 40, it remains one of Black Sabbath's most popular songs, as well as the band's highest-charting U.S. single until 1998's " Psycho Man ".
*Paranoid* est le deuxième album studio du groupe de rock anglais Black Sabbath, sorti le 18 septembre 1970 par Vertigo Records au Royaume-Uni et le 7 janvier 1971 par Warner Bros. Records aux États-Unis. L'album contient plusieurs des chansons emblématiques du groupe, notamment "Iron Man", "War Pigs" et la chanson titre, qui a été le seul tube du groupe à atteindre le Top 20, se classant à la 4e place des classements britanniques. *Paranoid* est largement considéré comme l'un des plus grands et des albums de heavy metal les plus influents de tous les temps, souvent cité comme une influence clé dans le développement du genre, ainsi que comme l'un de ses premiers albums. *Paranoid* a été classé à la première place de la liste des « 100 plus grands albums de metal de tous les temps » de Rolling Stone en 2017 et à la 139e place de sa liste des « 500 plus grands albums de tous les temps » en 2020. *Paranoid* a été le seul album du groupe à atteindre la première place du UK Albums Chart jusqu'à la sortie de *13* en 2013.

### Draft ###

### 1. Query Parsing

"évolution du succès commercial de Black Sabbath" → commercial success evolution
"entre leur premier album éponyme de 1970 et leur album Paranoid de 1971" → between debut 1970 vs Paranoid 1971
"critiques négatives... succès commercial considérable" → negative reviews + substantial commercial success

Key paradox: critical rejection ↔ commercial triumph. User wants explanatory factors.

### 2. Information Retrieval Phase

**Black Sabbath (1970):**
- UK: #8 position, sustained Billboard 200 presence >1 year
- US: #23 peak, certified Platinum both territories
- Critical reception: largely negative ●
- Impact: established foundation, heavy metal pioneer

**Paranoid (1971):**
- UK: #1 position (sustained longer) ●
- US: #12, 4M copies, no radio airplay ●
- "Paranoid" single: #4 UK, only top 10 hit ●
- Critical reception: initially unfavorable, later canonical

### 3. Commercial vs Critical Reception Dynamics

**Timeline factors:**
→ 1970: nascent heavy metal acceptance
→ 1971: genre consolidation, touring infrastructure development

**Distribution mechanics:**
Warner Bros. strategic patience? Delayed US release of Paranoid until Black Sabbath finished charting suggests careful market positioning.

**Cultural transmission:**
? Underground/club circuit adoption vs radio resistance
? Word-of-mouth acceleration patterns
? Demographic targeting hypotheses

### 4. Multi-factor Analysis

**Critical factors for commercial success:**
1. **Market timing** ● - heavy metal emerging as distinct genre
2. **Touring amplification** ● - 1971 US tour following Black Sabbath success
3. **Radio resistance paradox** ● - lack of airplay → cult following growth
4. **Industry strategy** ◐ - Warner Bros. release timing decisions suggest deliberate market cultivation

**Genre-specific dynamics:**
Heavy metal commercial success often emerges despite rather than because of critical establishment approval. Counter-cultural appeal → fanatical devotion → sustained commercial returns.

**Geographic considerations:**
UK vs US market reception patterns differ. Paranoid's UK success preceded US breakthrough by months - suggests different cultural adoption curves.

### 5. Uncertainty Acknowledgment

**Information gaps:**
⚠ Specific Warner Bros. marketing strategies
⚠ Tour booking data impact on album sales
⚠ Radio station playlisting decisions (or lack thereof)
⚠ Press/industry relationship evolution 1970-1971

**Logical constraints:**
Physical album sales data points suggest gradual market penetration rather than sudden breakthrough. Multiple factors likely interacted over extended period.

∴ **Conclusion synthesis:**
Commercial success stemmed from genre-cultural alignment + strategic distribution + touring amplification, despite/against critical establishment resistance. Heavy metal's counter-cultural positioning favored passionate grassroots adoption over mainstream critical approval.

**Key insight:** ! Commercial viability often emerges through non-traditional pathways when critical-commercial alignment breaks down.

### Answer###
L'évolution du succès commercial de Black Sabbath entre 1970 et 1971 présente effectivement cette apparente contradiction entre réception critique négative et succès commercial substantiel.

Pour leur premier album éponyme en 1970, Black Sabbath a atteint la 8e position dans les charts britanniques et a séduit une audience américaine en atteignant la 23e place du Billboard 200 pour plus d'un an, avec des ventes estimées à 4 millions d'exemplaires aux États-Unis. Cet album, considéré rétrospectivement comme le premier album de heavy metal, a ainsi établi les bases du succès du groupe malgré les critiques négatives de nombreux critiques musicaux.

L'album Paranoid en 1971 a radicalement renversé cette dynamique commerciale. Aux États-Unis, l'album a atteint la 12e position en mars 1971 et s'est vendu à 4 millions d'exemplaires sans presque aucune diffusion radiophonique. Le single "Paranoid" a quant à lui atteint la 4e place des classements britanniques, devenant le seul top 10 du groupe et démontrant une popularité commerciale supérieure à celle de l'album précédent.

Cette différence s'explique probablement par plusieurs facteurs. D'abord, le deuxième album bénéficiait d'une meilleure réception critique rétrospective, avec des éloges considérant Paranoid comme l'un des plus grands et influents albums de heavy metal de tous les temps. Ensuite, le succès commercial de Black Sabbath avait créé une base de fans dévoués qui ont probablement accueilli favorablement le nouvel album.

Les tournées de promotion, notamment la première tournée américaine du groupe qui suivait le succès de Black Sabbath, ont certainement contribué à renforcer leur présence commerciale. Cependant, les stratégies de distribution précises et les facteurs marketing spécifiques qui ont influencé cette évolution contrastée entre les deux albums restent complexes à analyser sans informations plus détaillées sur les décisions éditoriales et les stratégies promotionnelles de l'époque.
