The Afterthought brings back into focus the psychedelic sixties in all of their purple-haze glory, as seen through the eyes of legendary west coast music promoter and entrepreneur Jerry Kruz. Using the historical posters as a timeline, Kruzs recollections are a celebration of the resiliency of Woodstock-era arts and culture and foundational musical acts like the Grateful Dead, Janis Joplin, Steve Miller, The Collectors (Chilliwack), Tom Northcott Trio, Country Joe & the Fish and many more.

Complete with selected discographies and band biographies for many of the musical acts included in the book, The Afterthought is illustrated throughout with selections from the folk-inspired and psychedelia-fuelled artwork of legendary artists Bob Masse and Frank Lewis.
