In the location's words:

GRETCHEN's program as a (live) club reflects the complexity of current musical trends. From electronica, bass, drum'n'bass, dubstep, trap, IDM, electro, glitch, experimental, avant-garde to hip-hop, funk, soul, folk, afrobeats, jazz and world, GRETCHEN presents itself as absolutely open to any style.
GRETCHEN is multifaceted and stands for quality, experimentation, sophisticated and innovative sounds.
GRETCHEN is electronic to unplugged, presents DJ sets and live concerts. Musical quality of genre and artist are crucial, not limited imagination, narrow-mindedness or boredom.
GRETCHEN represents Berlin, gives national and international artists, their labels, but also newcomers a platform.
