A bit of info I found here: "Recorded in late 1966, the six songs on side one show the group at the peak of their power, with striking instrumental innovations and interplay which anticipate Jimi Hendrix and the Pink Floyd months before either had recorded. The Misunderstood's Glen Ross Campbell transformed the pedal steel guitar into a bucking, snarling monster of distortion, feedback and whine. He is one of the best unheralded rock guitarists; his playing suggests the missing link between the Yardbirds and Hendrix. A couple of the earlier cuts are not too much above the run-of-the-mill white blues of the time, but in all its gradual progress from garage rock to full-blown trippiness and hippydippiness, this shows consistent high energy. All I can say is, far out."
