Yes are an English progressive rock band that formed in London in 1968.
Their music is marked by sharp dynamic contrasts; often extended song lengths; abstract lyrics; and a general showcasing of its members' instrumental prowess.
Yes blends symphonic and other 'classical' structures with their own brand of musical style.
Despite a great many lineup changes, occasional splits within the group and the ever-changing trends in popular music, the band has continued on for nearly forty years and still retains a following.
Chris Squire, Steve Howe and Alan White of the band have announced the In The Present tour for late 2008 with vocalist Benoît David and keyboardist Oliver Wakeman.
