Just bought this cool recording of Joel Frahm's quartet live at Small's from February, 28th and March, 1st 2011 with Kurt Rosenwinkel, Joe Martin and Otis Brown III.
There's this tune by Frahm called "What's Your Beat?", track n.3 , a kinda funky piece with lots of bass pedals and not very much harmonic movement almost throughout the whole tune.
After Frahm's solo, Kurt digs in a series of sustained chords, probably using the Freeze function on his Hog controlled via exp pedal, but somewhat manages to change their pitch whilst they're held by the pedal. I've heard very closely and it doesn't seem like he's playing many chords, but just one and after freezing it he modulates its pitch (things made possible by Joe Martin holding a pedal on bass, allowing Kurt to somewhat be harmonically creative)..I've thought of some of those pitch benders which have a volume-like pedal, but still sounds very strange to me.
Did anyone hear it and figure out what's happening there under Kurt's feet/hands ?
PS For those who don't have it, I recommend buying it, definitely worth the money (you can purchase it directly from Small's website).
