April 8. Formed on Long Island, Vanilla Fudge is one of the pioneering acts of the hard-psychedelic sound that begat heavy metal (the quartet began in 1965 as soul rock outfit the Pigeons; the name change came after the addition of drummer Carmine Appice in 1966). The band's self-titled debut appeared in 1967 bearing their Top 40 smash cover of the Supremes' "You Keep Me Hanging On," and their thudding, organ-dominated style proved a starting point for Deep Purple and other budding hard rockers—in fact, Led Zeppelin's first US tour, in 1968, was as the opening act for Vanilla Fudge. This month, the Fudge hammers Daryl's House on their "Spirit of '67" tour. (Dave Alvin and the Guilty Ones testify April 22; Denny Lane plays Band on the Run April 28.) 8pm. $30. Pawling.
