The band’s first album, Cactus was one of the best hard rock albums of 1970.  The album opens with a fierce version of the Mose Allison song “Parchman Farm” (about the notorious Mississippi State Penitentiary of that name) – and not long after Blue Cheer recorded that classic blues song (misnamed “Parchment Farm”) on their debut 1968 album, Vincebus Eruptum – plus the Willie Dixon song “You Can’t Judge a Book by the Cover” that was made famous by Bo Diddley.  But Cactus’s own songs rock just as hard, like “Let Me Swim”, “Oleo” and “Feel So Good”.
