Brazilian psychedelic rockers Os Mutantes have been around since 1966 and are cemented as cultural behemoths. After line-up changes, break ups, and periods of silence, Os Mutantes are back with their ninth album titled Fool Metal Jack, written almost entirely in English. “Ganjaman” seems to be emblematic of the album, which is to say that it’s like what psychedelic rock would sound like if it had lounged on Brazilian beaches for like 40 years.
