The nice thing about J.J. Cale’s ”Cocaine” is that the lyrics are so strongly secondary to the sound of the song that their fractured linearity becomes an asset. If you want it to be an anti-drug song for you, it can be that. For most people, though, the attraction to the song is the driving guitar hook, and that’s true whether you’re enjoying Cale’s 1976 original version, or any of Eric Clapton’s several covers. Clapton’s studio version of ”Cocaine” off his solo album Slowhand is among his most enduringly popular hits. In concerts, Clapton often performed the song by beginning with a slow-developing, improvised-sounding guitar lead, building to the dramatic power riffs that open the familiar tune. Even for an artist like Clapton with a huge body of high-quality work, ”Cocaine” ranks among his best.
