1 price = 2 parties: Whether you're young or young at heart, age doesn't matter at this double party . The focus is on having fun with the music: two well-known Bremen DJs bring the sound of your youth, party classics from the 60s to the 90s(FOREVER YOUNG) to the dance floor - as well as selected gems from swing, pop, soul and global sounds(TANZ IM GLÜCK) in the second room.
