By their third album, Traffic had a reputation as fierce -- if indulgent -- purveyors of footloose, freestyle acid rock that was often as gentle and folksy as it was funk-fueled and groovy. John Barleycorn found Steve Winwood again pooling his influences and splashing through them vigorously. From the Motown R&B of "Glad" to the countryside troubadouring of "John Barleycorn," Winwood's piano and organ are buoyed by Chris Wood's sax and flute. It's clear that Traffic are a main influence on the jam band scene of the early '00s. This deluxe edition includes alternate takes and a 1970 live set.
