Formed in Warwick, England, the Edgar Broughton Band arrived on the London underground music scene in 1968. Led by the Broughton brothers, vocalist/guitarist Edgar and drummer Steve, and fleshed out by bassist Arthur Grant and guitarist Victor Unitt (who also briefly served with the Pretty Things), they soon signed with the Harvest label and issued their debut, Wasa Wasa, a collection of underground electric blues jams anchored by Edgar's Captain Beefheart-like vocals, in late 1969. The Edgar Broughton Band returned in 1970 with Sing Brother Sing, which reached the U.K. Top 20 and spawned a pair of minor hit singles, "Out Demons Out" and "Apache Drop-Out" (a fusion of Beefheart's "Dropout Boogie" and the Shadows' "Apache"). The group seemed poised for a major commercial breakthrough, but even as their brand of heavy rock was flourishing thanks to groups like Black Sabbath and Deep Purple, the Broughton Band made an about-face, and their music became considerably more quiet and politically charged. Their chart momentum stalled, and a 1971 self-titled effort failed to catch on.
