Deep Purple are pretty much the band that are credited with inventing heavy metal, so they're the ones to blame then. Ah no, each to their own and all that! In 1984, this classic band reunited in Melbourne for a gig that was talked about for many a year after. They had just made the album Perfect Strangers together and the concert featured performance of some of their classics such as the famous Smoke on the Water, which has one of the most iconic guitar riffs of the century in its opening. Yeah! Rock and roll! Sorry.
