I found out about this lot whilst exploring the music of Airto Moreira and Hermeto Pascoal. A singer called Googie Coppola features on a recording by one or both of those Brazilian artists. She’s the lady surrounded by three hirsute guys, above.
That video/link should take you to a playlist of their entire 1971 album. I’ve not listened to it much, as yet. Could be a steaming pile of kack! I hope not. I was intrigued… and aim to follow this initial post up with a proper listen, as soon as time permits.
