Yes


"Far and away the longest lasting and the most successful of the 1970s' progressive rock groups, Yes has proved one of the lingering success stories from that musical genre. The band, founded in 1968, has overcome a generational shift in its audience and the departure of its most visible members at key points in its history to reach the end of the century as the definitive progressive rock band."
