I don't consider smooth jazz as "Jazz". I prefer the Hard Bop and Bop era. However, my Sister gave me the Fourplay "Best of ..." CD for Christmas several years ago. It remained sealed until about a week ago. She listens to Rippingtons, Manhattan Transfer, Spyro Gyra, etc., and assumed that I'd like it. I scanned through each song, not expecting much, then came upon track 3 and played it TWICE. (This is coming from a guy with over 4,000 1950's jazz records!) The title is "Higher Ground", a song made famous by Stevie Wonder, featuring Take 6. I found it a fairly decent recording, funky, and fun to listen to. I can't stand the other 11 songs, but was pleased to find one worth listening to.
I'm not buying any of their other CD's though ...
