Headlining the one-day festival are Warp Records legends Plaid, backed up by an intimate show from Gazelle Twin just days before she headlines the Barbican in London.
Elsewhere on the bill, there's punishing guitar noise in the return of the UK's loudest band, Part Chimp, along with the hypnotic grooves of Kogumaza, necro-psych Londoners Taman Shud and prog-kraut legends Guapo. Manchester's ambient innovators Marconi Union play a one-off improvised set, and Arbouretum's Dave Heumann also performs as part of his debut European solo tour.
The festival takes place at The Bullingdon in east Oxford. Tickets are £15, and all profits to go Shelter's work fighting homelessness. You can buy tickets from www.wegottickets.com/audioscope.
