Deep Purple are remembered by most folks as the Ian Gillan-fronted hard rock band that recorded the iconic "Smoke on the Water," but as is the case with most recording artists, there's a whole lot more to the story, and in this case, the preamble part of Deep Purple's career might arguably actually be more exciting and interesting. The first incarnation of the band featured Rod Evans as the lead singer, and of course the guitar playing of Ritchie Blackmore, and if there's a better opening single for a band than Deep Purple's classic cover of Joe South's "Hush," well, there's little doubt "Hush" would hold its own.
