The Incredible String Band lit up the late 1960s music scene with their groundbreaking LPs The 5000 Spirits..., The Hangman's Beautiful Daughter and Wee Tam and the Big Huge, and were one of only five British acts at Woodstock. Their core duo Robin Williamson and Mike Heron then created further significant work both together and apart that was feted by Paul McCartney, Mick Jagger and Robert Plant, amongst many others, and this book uncovers the story and comprehensively examines all of the just short of one hundred original recorded works of what is the great lost band of the 1960s.
