Obscure British prog-rock band Mighty Baby evolved from a Mod group called The Action, but moved heavily into experimental psychedelia in 1969, when they cut an incredible debut for the Head label. Glastonbury Fayre Festival 1971 captures the legendary group in live action, A Blanket In My Muesli being a free-form jam that remains their best-loved effort; India is a similarly hefty instrumental mega-jam with lilting flute amidst the bluesy guitar work, and there are awesome renditions of Virgin Spring, Devils Whisper and Lazy Days. If you like your prog thoughtful, complex, and multi-layered, this ones for you!
