The band eventually got back to their plans of playing hard rock, and released "Deep Purple in Rock" in 1970, which became a big success. The famous album cover shows the band members' faces engraved into Mount Rushmore. The album itself had popular songs such as "Speed King" "Child in Time" and "Bloodsucker" (which was later re-recorded by the band in 1998). Critics and fans were pleased with new singer Ian Gillan's high pitched singing and screaming, and the album has since been considered a classic of the time, along with Black Sabbath's "Paranoid" and Led Zeppelin's "Led Zeppelin II".
