I don’t claim to be much of an authority on Brazilian progressive psychedelic folk music, but I’d wager this is considered one of the greatest albums of said genre. Satwa’s self titled 1973 record is the work of two guitarists, Lula Cortez and Lailson de Holanda Cavalcanti. These mostly improvised (I think) duets are beautifully raga-like, but the guitar style energizes the pieces in a way that produces something new and provoking. It’s great music to put on while doing something creative. I wish I knew more about Satwa, I stumbled upon them purely on accident. A great record and highly recommended, if you can dig it up.
