Circus Maximus was a United States band in the late 1960s, who combined influences from folk music, rock, and jazz into a form of psychedelic rock.
The band was formed in 1967 by Bob Bruno and Jerry Jeff Walker. Bruno's song "Wind", from their eponymous first album, became a minor hit in the United States, particularly through airplay on "progressive" FM radio stations.
I stumbled across this band & song around a year ago while looking for material by another technical rock band named Circus Maximus also.
This song 'Wind' released in 1967 has a unique sound & recording that grows on a person after listening to it a couple of times.
The Folk influence with the Jazz is very different in style, especially the folk guitar throughout the song.
