Deep Purple in Rock, also known as In Rock, is the fourth studio album by English rock band Deep Purple, released on 3 June 1970. It was the first studio album recorded by the Mark II line-up. Rod Evans (vocals) and Nick Simper (bass) had been fired in June 1969 and were replaced by Ian Gillan and Roger Glover, respectively.
Deep Purple in Rock was the band's breakthrough album in Europe and would peak at No. 4 in the UK, remaining in the charts for months. (The band's prior MK I albums had been much better received in North America than in their homeland.) An accompanying single, "Black Night" reached No. 2.
