There will be smoke on the water wherever you walk with this Deep Purple shirt. Formed in Hertford in 1968, the band is considered to be the pioneers of heavy metal and modern hard rock. Despite this fact, they have changed their musical approach over the years. They were originally formed as a progressive rock band but shifted to a heavier sound in 1970. The band, along with Led Zeppelin and Black Sabbath, has been referred to as the“unholy trinity of British hard rock and heavy metal.” The band was ranked number 22 on VH1’s Greatest Artists of Hard Rock program and they were inducted into the Rock and Roll Hall of Fame in 2016.
