Peter Walker

In the late ’60s and early ’70s, Ravi Shankar disciple Peter Walker zeroed in on the kind of heady, raga- and flamenco-informed folk championed by his better-known contemporary Sandy Bull. After decades off the scene, Walker reemerged back in ’08, and here he plays behind last year's release of a never-before-issued 1970 set, Has Anybody Seen Our Freedoms?
