Even in an age of unparalleled innovation and artistic freedom, Spirit stood head and shoulders above their 1960s-era rock 'n' roll contemporaries. Perhaps only Love shared the same sort of expansive and adventurous artistic vision as the five guys in Spirit, whose disparate and diverse musical backgrounds led them to explore the outer regions of rock 'n' roll as the band incorporated elements of the blues, folk, R&B, and jazz into their heady brew of psychedelia-tinted hard rock. Although they never experienced the level of commercial success that their talents and innovative music deserved, few bands since have matched Spirit in eccentricity, originality, intensity, and instrumental virtuosity.

For all their creative accomplishments, Spirit's legacy is that of a half-forgotten band whose name is seldom brought up in 'classic rock' discussions. Spirit on track corrects this oversight, revisiting the band album by album, song by song, from their ground-breaking self-titled 1968 debut and their masterpiece, Twelve Dreams of Dr. Sardonicus through the break-ups and reunions and solo efforts of the lean years until their resurgence in the 1990s with albums like Tent of Miracles. More than a mere album guide, this book recounts 30 years of the trailblazing artistry of Spirit.
