"Spanning a decade of live performance, this 5CD boxset exposes some of the strengths, weaknesses and internal power shifts that characterised Quicksilver's 14-year career, with Valenti cast as both hero and villain. The contents - four gigs from 1967, 1970, 1976 and 1977, and a rehearsal from 1970 - sadly omit anything from 1968 (the year they recorded their best album, the psych-blues classic Happy Trails), but the inclusion of a February '67 Fillmore concert allows us to hear Quicksilver in the period following the Human Be-In, the headline-grabbing event in Golden Gate Park on January 14 that established San Francisco as the emerging epicentre of the counterculture".
