koenji cave is a psytrance-focused bar and event organizer based in the koenji neighborhood of tokyo, running club nights and outdoor raves under various series. matsuri digital is the label and production outfit founded by tsuyoshi suzuki and dj yuta in 2013, continuing the lineage of matsuri productions, the goa trance label suzuki co-founded in london in 1994.
this event is a 24-hour non-stop outdoor rave held at ooba camp village, a campsite outside the city that koenji cave has used for previous open-air editions. the collaboration ties the event to the matsuri digital catalogue and specifically to prana's "sense of unity" album, celebrating the project's 30th anniversary, with programming across live and dj formats drawing from the goa and psytrance axis.
