Eric Clapton's concert at the Royal Albert Hall, London, Britain - 1990As big a rock star that he became, Eric Clapton remained a reserved personality. So a lot of what is revealed in the terrific bio film “Eric Clapton: Life in 12 Bars” (Showtime, 9 p.m.) is a revelation, from a shocking young life to his immersion in an art form he found through a kids’ radio show, the blues. As a guitarist, he was a teen prodigy, who found his way to the Yardbirds, but quit when their pop tendencies took him away from his interests. He created a new sound for electric blues with John Mayall, and an explosive new hybrid in Cream, an experience that nearly burnt him out.

His searching was echoed in his work in Blind Faith, but he was destroyed by his love for the wife of his friend George Harrison, Patti, a yearning that created Derek and the Dominos’ singular album “Layla and Other Assorted Love Songs.” Heroin was a setback, but not nearly as bad as alcohol, we learn in Lili Fini Zanuk’s film and the whole of his 80s output is dismissed as a lost weekend. The shocking death of his two year old son (from a 53rd story window) led to a reawakening (and Grammy rewards) and he lives now to help others in recovery. It’s quite a portrait, with a terrific soundtrack.
