If not as consistently a knockout as Spirit of '67, Revolution! is nevertheless right on its heels, containing as it does an even greater degree of pop experimentation within the form. Suffice to say that this group managed to make the transition from the simple, tough R&B-flavored rock they helped found to the more psychedelic popcraft/acidic majesty that soon unfolded behind the 1964-1965 Beatles' lead. And if Spirit is the Raiders' Revolver, then Revolution! is their less wacked-out Sgt. Pepper. Beginning with one of their most supreme moments -- the rough-and-tumble, aggressive yet amazingly catchy "Him or Me -- What's It Gonna Be" -- the LP takes the same twists and turns as its predecessor through a multitude of entertaining styles, from the sharp laze blues of "Reno" to the quintessential upbeat smack of "Mo'reen" and especially "Gone-Movin' On." Through it all, bandleader Mark Lindsay is a minor marvel. Lindsaymay not have been blessed with a classic pop voice croon, but his exciting lower-range grunt and snarl compliments his upper-range prettier voice in a way that adds bushels of unfiltered attitude. His gutsy, versatile style totally blends with the rough edges of both the production and playing, which belies the more gilded pop moments. Lindsay is the glue that holds what would have been a willy-nilly collection together. Truly 1967 was the most magical year in pure pop history. But if many with-it fans have already bathed in the unbelievable sonic pleasures of that year, far too few have given the Raiders their rightful place in this pantheon, even though they certainly held such a place in their time. There can be no reason for this oversight to continue, for here is the evidence once again laid bare.
