"To balance out all the incense and peppermints sentiments, March of the Flower Children includes ample material from some of the era's more snarly and cantankerous artists, with noisy disruptions from the Velvet Underground, Captain Beefheart, and the Mothers of Invention. With 85 tracks and close to four hours of sound, March of the Flower Children illuminates the entire spectrum of 1967's tuned-in, turned-on, and dropped-out psychedelia".
