Deep Purple were so much more than “Smoke on the Water.” They were a hard rock band with an organ that often was heavier than the guitar, they incorporated classical music motifs while singing about racing cars in space, and their drummer owed more to Buddy Rich than anyone else. They were so much of their time that, in theory, they should sound like the most dated band in the world. This is not the case at all.
The genius of Deep Purple relies on their pomposity, although not in the way most people have assumed. Yes, they were overblown and quite pretentious; but what makes them amazing is that they were all that while remaining true to rock n’ roll in terms of excitement. They could make a ten minute song sound as incendiary as a two and a half minute punk song.
Take something like the live version of “Space Truckin’.” It’s filled with complicated passages and arrangements but it’s never less than a bulldozer blazing down the highway. They used their musicianship to make music of the most intense order. Stretching the song past ten minutes, it eventually seem like the Earth is being ripped in half while you keep headbanging.
It’s the essence of metal: challenging music played in a brutal way that makes your body react. That’s why they, along with Black Sabbath, are the undisputed fathers of the form. Deep Purple went a step ahead and made low cultured baroque music as exciting as the most sophisticated and avant garde styles in rock, and they still feel timeless nowadays.
