B-movie junkies, gather round and prepare yourselves for what could only be described as a cinematic speedball. Take a combined hit of two of the most potent strains of toxic cinema, dress it up in ritualistic robes and make it dance to the beat of a stoned, motorik, country commune soundtrack.

Like an exploito double bill where both films merge into a single feature, this directorial debut by an ex-Roger Corman protege and future Russ Meyer art director (another heady cocktail) is the product of one writing duo’s fleeting time in the driving seat as the moviedrome marathon approached its dwindling finish line.

In 1988, Savage Pencil’s superb compilation Angel Dust alerted collector nerds to hidden caches of Biker Movie Soundtrack albums, and battered copies of Satan’s Sadists, The Wild Angels, and Hell’s Angels on Wheels, bristling with gasoline surf guitars and hack psychedelic travelogue tunes, were swiftly snaffled.

The 1971 lycanthropy-biker flick Werewolves On Wheels lack an official soundtrack album, despite featuring future Steve Miller sidekick Don Gere, so Finders Keepers have assembled one.

Droning acid-rock ritual grooves are doused with tailpipe noise, between oddly sentimental country songs, and solemn satanic incantations. Expect the hypnotic title track to become a much sampled staple.
