Best rock & roll singer ever, Ian Gillan. Who else could've sung the part of Jesus on the "Superstar" album. Jon Lord, the musical director of this band, classically trained, yet outrageously creative. Ian Paice, the manic atomic clock driving the beat of the band. And Ritchie Blackmore, the gifted showboat of the band on guitar. This album was the first of several popular albums by DP, all of which bore songs destined to be classic rock gold. If you odn't have this album, get it. Rock & roll will never die.
