Best experienced live, the Abbey Road session captures the underground’s favourite anarcho-Brum scruffs extemporising in front of an invited audience on the likes of perennial festival shout-athon “Out Demons Out”. By the time of 1972’s Inside Out, they’d dropped the Beefheart mannerisms and eased off on the agit-prop in favour of stoner country-rock. The following year’s Oora even has David Bedford arrangements and soulful backing vocals from Madeline Bell. Never really having the chops for the more sophisticated stuff, they should have stuck with being the English MC5.
