British Broadcast, 1976

By the mid-70s, Carlos Santana had nothing left to prove. Having led his group through seven albums of psychedelicised Latin rock and exploratory jazz fusion, he'd established himself as one of the era's most revered guitar gods, and his band, Santana, as some of the wildest live performers of the era. On the cusp of releasing yet another album of scintillating fretwork, 1977's freewheeling Festival, the Mexican-born virtuoso brought his carnival of sound to London's Hammersmith Odeon on 15 December, 1976, for a broadcast performance for the ages.
