intact expanda is a one-night club event run by the solartech collective, held at catonium, an indoor venue in hamburg that includes hotel accommodation on site. the event runs on a single floor with a hard capacity limit and no expansions to the guest list once sold out.

solartech has been active in the northern german psytrance and psytech scene for a number of years, and intact expanda is one of their recurring indoor editions, built around full-energy dancefloor programming in a contained, single-room format.
