a donation-based club night held at the autonomes zentrum, a long-running autonomous cultural centre. the night runs across three and a half floors covering zenonesque, goa, and suomi sounds on one floor, techno, hard groove, and trance on another, breaks, progressive house, and tech house on a third, and a bar room running nineties and two-thousands music.

it takes place on the traditional german "tanz in den mai" night, the evening before the first of may, when clubs across the country run special events to mark the transition into may. this edition is the autonomes zentrum's own take on that tradition, rooted in the goa and psytrance end of the spectrum rather than the mainstream club fare that dominates most of the city's offerings that night.
