Q: I think too many people are assuming that they are buying a compilation CD when they pick up this release. In fact, this was the original album released in 1957. Ella gets top billing becuse she was the biggest of the three "names" at the time. These sessions were laid down between Jan 4, 1956 and April 30, 1957. Each artist gets a chance to showcase their talents and it is apparent that, when they all get together for the few numbers that they all share, they are really swinging and having a great time. Basie's band was in top form, the arrangements were wonderful and the vocals are spot on. This is a terrific window into the past.
A:
Positive
