In 1996, the Backstreet Boys released their debut album, &amp;quot;Backstreet&amp;#39;s Back.&amp;quot; &amp;quot;Millennium,&amp;quot; &amp;quot;Black &amp;amp;amp; Blue,&amp;quot; &amp;quot;Never Gone,&amp;quot; &amp;quot;Unbreakable&amp;quot; and &amp;quot;This Is Us&amp;quot; followed. After parting with the group years ago, Kevin Richardson (second from left) rejoined A.J. McLean, Howie Dorough, Nick Carter and Brian Littrell. In March, they confirmed that they would be doing a limited Vegas residency as well as a new album and tour. Here are some other boy bands to scream over.
