Mighty Baby

Mighty Baby was formed in 1968 by ex-members of The Action, who'd been evolving from beat to mod to psych, and remained active until 1971 as a UK hippy prog outfit. Typically British but very wide-ranging, they bridged many rock / prog styles, with blues and folk elements (comparisons include: Wishbone Ash, early Hawkwind, Magic Muscle, etc.), and not unlike Quintessence a few members got heavily into Muslim philosophy which had a significant impact on the music as well. Some quote them as the British Grateful Dead. To many they're known for the live recording A Blanket In My Muesli on Glastonbury Fayre - The Electric Score (UK 1972) (opens in a new tab), which sees them jamming in the vein of freeform extended Man or The Grateful Dead. There is more material in this vein on the Live In The Attic and Tasting The Life: Live 1971 archive collections.
