I'm so glad someone mentioned Jose Gonzales' Veneer CD. I'm so in love with this record; have been playing it over and over this week and I too, was curious how he was accomplishing some of his stuff. My wife has a few years training in classical guitar and tells me that everything he is doing is doable in real time with classical techniques but I suspected that he might be looping. There is one tune where he has a bass run on one string against chords and he either looped it or accopmlished it himself with Buckethead sized hands (saw him last night........................what freakishly long hands that monstrous guitarist has). I got curious and picked up a beater classical guitar that we have and tried figuring out one of his tunes and actually made some progress (and I'm a terrible guitar player, technically speaking). I know that the percussion that he plays is doable in one of the later songs because that is a technique I've stumbled on as a percussionist which is either putting the guitar into an open tuning or fretting a chord appropriately and the banging your fist on near the sound hole to get a bass drum sound while the guitar chord plays very quietly as a sympathetic vibtration. Still, he might be looping. I hope so only because this is the best acoustic singersongwriter record I've heard since dear Eliott Smith passed away. It's so zen simple and he has the most beautiful, clear and untheatrical voice.
