Fred Hopkins was amazing. He was a such a badass player. There is really no other way to put it. Everything he played was awesome even his fat and twanky amp sound. He was part of the innovative quartet (the fourth member being silence or air) with Henry threadgill and Steve McCall. They redefined trio improvising as well as how ragtime could sound (see the "Airlore" lp). his work with 'cellist Deidre Murray both in duo and the Threadgill sextet was fantastic. My favorite example of his work is in trio with Peter Brötzmann and Rashid Ali on an FMP cd called "songlines". Pretty much every note he played had so much weight and power to it. I saw him play the night I got my first double bass with David Murray. In the first piece Murray took a mediocre post bop solo, John Hicks took an amazing post bop solo and then Fred layed the bass on it's side and started whipping it with his bow while Andrew Cyrrile sang into his snare. fantastic.
