In 1972 Lee Pickens left to form the Lee Pickens Group (LPG) and released the album "LPG" in 1973 on Capitol Records. Jim Rutledge also left Bloodrock in 1972, later releasing a solo album in 1976 on Capitol Records titled "Hooray for Good Times". Bloodrock replaced Rutledge on vocals and Pickens on guitar with Warren Ham on vocals, flute and saxophone. Stevie Hill on keyboards adjusted to Ham's presence by shifting his own style. These changes to personnel and style moved the hard rock sound of the band in a lighter direction, more toward progressive rock, pop and jazz, alienating some fans. The subsequent album, "Passage" was the last time Bloodrock visited the charts. It peaked at number 104 on the Billboard 200 in 1972.
