The most famous riff in rock — and one of the most misunderstood. Ritchie Blackmore played the Smoke on the Water riff in parallel fourths (not power chords) on a 1968 maple-neck Stratocaster through a 100W Marshall head, with a Hornby-Skewes treble booster adding clarity and just a touch of hair. The riff was tracked at the Grand Hotel in Montreux, December 1971, after a fire burned down the original recording venue.
