BAP, a prominent rock band from Cologne, Germany, was formed by Wolfgang Niedecken in 1976. Their music is a blend of rock, blues, and folk, with lyrics often written in Kölsch, the dialect of Cologne, which has played a significant role in their unique identity and regional appeal. Their thoughtful, socially-conscious lyrics and distinctive sound quickly garnered a dedicated following. Wolfgang Niedecken not only fronts the band but also is the main songwriter, infusing his works with reflections on societal issues and personal stories.

Over the years, BAP has become one of the most successful rock acts in Germany, releasing more than a dozen studio albums and achieving numerous chart successes. The band's strong local roots have not prevented them from gaining international recognition, as they've toured extensively beyond Germany. Their recent releases, such as "Radio Pandora" and its acoustic counterpart "Radio Pandora - Unplugged," showcase the versatility and enduring appeal of the band by revisiting some of their songs with new arrangements. The album "Vun Drinne Noh Drusse" further cements their status as stalwarts of the German music scene, with its title translating as "From the Inside to the Outside," potentially reflecting on both personal transformation and social change. BAP's commitment to authenticity and its colloquial storytelling continue to win over fans and affirm their legacy in the pantheon of German rock music.
