I've been listening to The Complete Science Fiction Sessions. On Rock the Clock I hear what sounds like a wha-wha guitar.
The musicians listed are Ornette, Dewey Redman, Charlie Haden and Ed Blackwell. Ornette plays alto and violin, Dewey, tenor and musette. All are distinguishable but I don't hear a bass (though there's a lot of bass drum). Is this just my old ears mis-hearing? Is Charlie playing wha-wha electric bass or something? What's going on?
