the flipsyde is a recurring indoor club night held at den aalmoezenier in antwerp, running psytrance through the main portion of the night and closing with a hi-tech hour. the series grew out of an earlier promoter project called raverse, rebranding under the flipsyde name and continuing to book a mix of belgian and international artists. editions run several times a year, typically across autumn, winter, and spring.

decoration is handled by unown deco, with face painting by infinity forest on the floor. the night operates a strict no-backpack, no-minors policy with id checks at the door.
