Mark III's first album, "Burn", released in 1974, was successful and seemed to point a positive picture for the band's future without Gillan or Glover. The singing harmonies from Coverdale and Hughes had something of a blues and funk style to them. These styles were explored more on the band's next album, "Stormbringer", released later the same year. Ritchie Blackmore left after he became more unhappy with this style of music, feeling it was just "shoeshine music".
