There are at least 2 BAP, 1) A rock group from Cologne. 2) A Basque Hardcore fusion band.

1) A rock group from Cologne (Köln), Germany, founded in 1976. Their most outstanding feature has been that all the songs performed by BAP are in Kölsch, the local ripoarian language (or German dialect) spoken in Cologne and its vicinity, which is hardly understood in other parts of Germany. BAP had their greatest successes in the 1980s, when they stormed the national charts with a number of subsequent singles. Their all-time number one is "Verdamp lang her".

During the peace movement in the 80s they played concerts on demonstrations and were dedicated to the disarmament in Germany and Europe.

2) BAP!! (Brigada Anti Polizialak) is an influential Basque Hardcore fusion band. Formed in 1984 and disbanded in 1996, they only released 3 albums partly because the drummer joined Negu Gorriak but achieved the cult band status thanks to their open minded fusion of styles and powerful live performances. Later 3 of the members formed Inoren Ero Ni.
