My next booking is at an underground party in Helsinki later this month with an interesting lineup of techno, bass, experimental and shamancore music!
The organizer is Hytky:

HYTKY is a longstanding, non-profit techno music organisation located mainly in and around Helsinki, Finland. We are a student organisation registered under the University of Helsinki since 1996. We focus on late night, underground techno parties. HYTKY is a creative collective with a strong non-commercial DIY tradition where MUSIC, AMBIENCE and PEOPLE come first.
