In all honesty I think Acid jazz is really defined by the repeated figure and simplicity of the groove often with sometimes only one or two chords stretched out (sounds sort of like a definition of modal jazz eh?). Listen to Some St. Germain. They basically did the best job at the genre IMO.
Nice little groove that sits well inside of the Acid Jazz from the early 70s. Reminds me of Eddie Harris's electric sound, especially with the your "limited" microphone cutting out the dynamics. Not intentional I'm sure, but surprisingly similar.
