Nothing signals exclusivity quite like holding a one-day techno festival on an island only accessible for eight hours a day. During the other 16, Osea Island is cut off by the tide, adding even more enigma to Lost in a Moment, a peripatetic event that almost goes out of its way not to attract attention – as with early rave culture, it doesn’t even divulge its whereabouts until shortly before blastoff.

Club promoters the Hydra are behind it and the Berlin label Innervisions provides the four DJs. House/electronic specialist Marcus Worgull opens the day with what is in effect background music. It allows the crowd of 500 a leisurely hour to explore the island’s facilities, which include a donkey paddock, decommissioned torpedo boat factory and complimentary bikes on which dozens amble along the gravel roads.

Revered duo Âme are next, splitting in half to play separately. Kristian Beyer, who flies the flag for Kraftwerk haircuts, creates a house party environment with a cache of well-loved techno tracks and high-stimulation new ones. Frank Wiedemann does much the same but live, mixing world music and Afrobeat snippets into a sinuous tech-house stew. The elfin Dutch DJ Job Jobse takes over with two hours of tech-house as night falls on the tree-lined courtyard. Glitterballs dangling from branches turn it into an enchanted Ibizan garden, albeit one with the intermittent drizzle that signals autumn in England.

All the DJs return for an eight-handed closing set that finishes with the crowd singing Happy Birthday to Beyer. Appropriately for this otherworldly event, there’s a long wait before the tide recedes enough to allow exit from the island.
