Machine HeadDeep Purple
One of the giants of rock and the album that out them there. The legendary first chords learned by a generation of guitar players was the opening riff from the rock anthem Smoke On The Water. Richie Blackmore's guitar icon status aside, the secret sauce of Machine Head is Jon Lord's revolutionary sound design created by piping his Hammond organ through a Marshall amplifier, giving Deep Purple a key component of their signature sound. A landmark album front to back.
