I've never heard of Os Mutantes. I love the album cover. "Panis Et Circenses" is a very 60s sounding song. I'm enjoying it a lot. It's very Beatles-esque. There's so much going on across this song - I love the trumpet (?) going crazy. "A Minha Menina" has me moving right away. "Adeus Maria Fulo" is a very weird song, and I love it. The noises in the background remind me of the White Lotus season 1 intro. "Senhor F" is great. "Ave Genghis Khan" has sweet synth business going on. I don't want to be reductive, but these guys sound like the brazillian beatles to me. They have a lot of the 60s psychedelic british sound in their music. They are doing a lot of weird experiental noises, but I'm enjoying all of them. I've gone down a wikipedia rabbit-hole reading about the Tropicália movement in Brazil. I enjoyed the entire album. It was weird, fun, and a great length. 9/10
