This superb LP from alto saxophonist Lou Donaldson's early days on Blue Note was discussed in a post in March 2013. All the background and availability information is still relevant, so you can click here to read it.
The track contained in the previous post was the laid-back Day Dreams, which was put on the "B" side of a single to promote the album to jazz radio stations.
Here's something from Lou Donaldson's funk period in the late 1960s. Jazz purists scoffed at these recordings of course, but a lot of people dug them. This is from Mr. Shing-A-Ling (Blue Note, 1967).
