Snow goose brings me back to the seventies round at a mates house. Up in his room in a large Victorian semi a bunch of us would gather maybe after the pub, a few joints, occasionally mushrooms or other psychedelics and he'd put on albums. So there would be Gong, Daevid Allen, Fish Rising from Hillage, Grateful Dead live Dark star). Maybe classed as more Hippie than prog. But offbeat prog albums would be Camel, Jade Warrior, Edgar Broughton (Oora), Soft Machine, Kevin Ayres. As well as the more obvious stuff. Saw Tractor at Deeply Vale free festival. Any other blues go?
