Circa is a band of veterans, formed by former Yes members Billy Sherwood, Tony Kaye and Alan White. In Circa, they team up with guitarist Jimmy Haun to go off on an adventure into the past and present of progressive rock. Hints of the 70s, 80s and 90s show through in all compositions by this band, which at the same time are 100% 21st century progressive rock songs.

In 2007, the band released their debut album Circa:2007, which is sold solely through the band's own web site, adding an even more 21st century touch to the old prog influences.
