Toncho Pilatos - 1973
This little slice of Mexican psychedelic rock sounds like Jethro Tull, Can and Os Mutantes rolled into one; and that's just the first song. With a flute, a Wurlitzer piano, incredible hard rock guitar work, heavily reverbed vocals and wild time signatures that change on a dime, the most amazing thing about this album is that nobody seems to know about it. Released back in 1973 this LP gathers up all the great elements of psychedelic rock up to that point and puts them all in one place. As an added bonus, most of the vocals are in Spanish, so you don't have to hear all that hippie drippy crap about goblins, wizards and gnomes - because you know that's what they're singing about.
Fine, fine music.
