“It’s some thunder in my brain”

Deep Purple’s 1968 debut Shades Of Deep Purple has only a hint of the explosive contribution that Purple would make to metal’s birth a couple of years later but it can be heard clearly and excitingly on the album’s Side-B opener Mandrake Root. It’s a great, funky rocker that makes sterling use of the E7#9 “Hendrix” chord and some raunchy crooning from the band’s normally mild-mannered original singer Rod Evans. But it’s when the band launch into a short bass-propelled instrumental freak out that sparks start to fly. In their live sets the band would use this track to launch into huge jamming extravaganzas. Here, it’s kept fairly brief but it still allows the band to tap into the sonic danger that they would become known for. Guitarist Ritchie Blackmore, a tentative presence on the rest of the album, blasts out some violent, noisy tremolo abuse that is the record’s strongest shade of the Deep Purple we all know and love.
