Conspiracy was a progressive rock band founded by Billy Sherwood (formerly of Yes) and Chris Squire (bassist in Yes). The band has released two albums: Conspiracy (2000) and The Unknown (2003), and a live DVD (2006), but is currently inactive.
Squire and Sherwood had formed a strong writing partnership, but events were to see Sherwood pushed out of Yes before he had officially joined. A reunion with Anderson Bruford Wakeman Howe left no official role for Sherwood, although one Squire/Sherwood composition, "The More We Live—Let Go", was released on the Yes album Union (1991). Sherwood played most of the instruments on the piece, including bass.
The years passed—work continued on and off on the material while Sherwood's relationship with Yes went through many phases—when finally, in the late 1990s, a release under the Chris Squire Experiment name was announced, an album to be called Chemistry.
However, again, events in the Yes camp took over. Sherwood officially joined the band in 1997 and the band moved to new management and a new record label. Although Yes had recorded new material in late 1996 with a previous line-up, this belonged to a different record label (who released it on Keys to Ascension 2 later in 1997). The new label wanted an album recorded quickly and, to this end, two tracks from Chemistry ("Open Your Eyes" and "Man in the Moon") were re-worked by Yes for Open Your Eyes (1997).
Squire and Sherwood share lead vocals on the album, with Squire playing most of the bass parts and Sherwood playing most of the guitar and keyboard parts, plus contributing some drumming. The name Conspiracy was intended to represent Squire and Sherwood's desire to collaborate with different musicians. The album included appearances from White, Haun and World Trade drummers Jay Schellen and Mark T Williams. Conspiracy also included one track based on a set of sessions involving Squire, Steve Stevens and Michael Bland: "Violet Purple Rose" consists of a recording from the sessions with overdubs from Sherwood.
Shortly after leaving Yes in 2000, Sherwood had announced a project called The Unknown including brother Michael, Haun, Schellen and Jonathan Elias. Nothing more came of this, but the title track of the Conspiracy album was co-written with M. Sherwood and Haun and derives from those earlier plans.
A live band was assembled in 2004 with Squire (bass, vocals), B. Sherwood (guitars, keys, vocals), Schellen (drums), M. Sherwood (keys, vocals) and Scott Walton (keys). They rehearsed, but touring plans were abandoned. However, a private live show was recorded and released on DVD in 2006. Their set included Conspiracy tracks, material from Open Your Eyes and from Squire's 1975 Fish Out of Water solo album.
(Kaye and Green have worked with Sherwood on a number of recent projects.) However, in 2007, Sherwood announced that this project, called Psy-Op, will be released under a different name and, while finished, will be put back so as not to compete with Sherwood, Kaye and White's new band, Circa:.In a late 2007 interview, Sherwood said, "I don’t foresee another Conspiracy record, simply because Chris lives in London and I live here in the States. I’m doing Circa now and he is doing his own thing. We have drifted apart in terms of working together simply by location/geographically more than anything. I’m enjoying playing bass a lot right now, my focus is on Circa and obviously Conspiracy is dear to my heart, but it took a turn and went into a dormant mode here so really see anything in the future right here at the moment."
