The Belgian band Opmoc plays on a stage at the Brussels Jazz Marathon in the Grand Place, Brussels. Originally the city's central market place, the Grand-Place is now a UNESCO World Heritage site. Ornate buildings line the square, including guildhalls, the Brussels Town Hall, and the Breadhouse, and seven cobbelstone streets feed into it. In the background, behind the stage, is the Maison du Roi (or Broodhuis / &quot;Bread House&quot;) which houses the Museum of the City of Brussels.
