Nothing can truly prepare you for your first listen to Os Mutantes. All the hype in the world can only pique your interest...of all the countless reviews I've read, none have ever captured the essence of the band, and I'm not about to attempt it here. Any song from their first album could be my choice here...the psychotic carnie music of "Panis et Circensis", the drugged-out doo-wop of "Baby", the Ray Davies-informed songcraft of "Senhor F" or the Donovan meets Alistair Crowley creepiness of "Trem Fantasma". So I chose this, their best-known freakout. Go find out for yourself.
