“Donovan never really gets the credit he deserves for kicking the future into motion. I’ve said that already, I know. But seriously, here he is detailing an acid trip in all its cool-and-gone poetic glory at least half a year in advance of the Beatles Sgt Pepper. And better yet, he keeps the groove bluesy, the whole thing strutting comfortably along, the sunshine superman in full cosmic bloom. Nothing could stop him but a drug bust, which is precisely what happened.” (Philip Random)
