Indeed!
I got the Ferguson Mosaic (finally) but these 2-fers are a lot more convenient. Except for the first one (white cover) that was half Ferguson and half Herbie Mann. For some reason they only used cuts from the dance albums, which are good (enough), but the meat is on these four + a few others.
It was a good band with a good book. Willie Maiden, Slide Hampton, and Don Sebesky were the main writers, and then post-Roulette, Mike Abene cam in and did some good work,
