ビリー・シャーウッド
Circa 2007 (stylized as "CIRCA: 2007") is the debut album by Circa, a progressive rock band consisting of then former Yes members Billy Sherwood (bass, vocals), Tony Kaye (keyboards) and Alan White (drums), as well as Jimmy Haun (guitar), who had worked with Yes as a session musician. Billy's elder brother Michael Sherwood also appears. Two tracks are based on material Billy Sherwood and Trevor Rabin were developing in the mid-1990s.
