This is such heavy and sweet tune!
Proper jazz funk for serious dancers. There are some heavy weight players behind this, formerly known as The Jazz Crusaders. Played by the usual suspects, GP and TP et all, but I've also seen Dj's like Harvey spin this.
It's Off the 1977 'Free as the wind' LP and if you like to mix up with some jazzy styles there are no reasons to ignore this tune!
Hope you dig!
The Crusaders - Sweet n' sour (192)
