Before they became 2/5 of Vibracathedral Orchestra over 20 years ago, Julian Bradley and Neil Campbell had been playing as a duo, with a series of cassette releases, a few live performances and a vinyl LP on John Olson's American Tapes label. During this time they laid the foundations for the more elaborate constructions they'd later inhabit with Vibracathedral, cranking out long-form phasing drones that mixed guitars, feedback and electronics with violins and all manner of acoustic bric-a-brac. Since the formation of the band, duo sightings have been fleeting - a few gigs, a festival appearance at Colour Out of Space and the 2016 "FOR LILA O" album - so this will be a rare opportunity to hear these long-term collaborators in a stripped-back form.
