An album called Macbeth by the Third Ear Band. They wrote the score and performed the soundtrack to Roman Polanski's film version of Macbeth. Instruments include the oboe, viola, recorder, drums, cello, bass, guitar, violin.
AMG quote "Although they were loosely affiliated with the British progressive rock scene of the late '60s and early '70s, Third Ear Band was in some ways more of an experimental ensemble performing contemporary compositional work. For one thing, they didn't use electric instruments, or even guitars, instead employing violin, viola, oboe, cello, and hand percussion. More important, they didn't play conventional rock "songs." They featured extended instrumental pieces that often built up from a drone, or hypnotic pattern, to a dense, raga-like crescendo. Their "progressive rock" tag probably arose because they recorded for Harvest Records, Britain's leading art rock label, which was home to Pink Floyd, Kevin Ayers, Pete Brown, Edgar Broughton, and many other progressive acts."
Their debut release Alchemy sounds interesting, but I have not had the chance to hear it yet.
AMG quote "Third Ear Band here makes excursions into improvised chamber music. In the opener, "Mosaic," which is at seven minutes one of the longest cuts, guitar meets recorder and violin in a disharmonic free jazz summit that fades away before building into a trancy mini-crescendo. On "Stone Circle," recorder lines interweave over an unadorned drum's repetitive rhythm. At times the recorder lines are so fluid and unnatural they sound like they're being played backwards which indeed they just might be. Generally the remainder of the tracks run the course between half-structured improv and droning chaos. Comparisons could be drawn to Soft Machine or the Dream Syndicate, but neither quite has the sense of "collective first" nor the repetitive insistence of Third Ear Band."

Another album, Strategies Against Architecture II by Einstürzende Neubauten.
AMG quote "Along with Cabaret Voltaire and Throbbing Gristle, Germany's Einstürzende Neubauten ("collapsing new buildings") helped pioneer industrial music with an avant-garde mix of white-noise guitar drones, vocals verging on unlistenable at times, and a clanging, rhythmic din produced by a percussion section consisting of construction materials, hand and power tools, and various metal objects."
