To make the bloody thing talk the way I do when I'm on a verbal roll, in my idioms and rhythms.
The ability and desire to transform the mundane materials at hand that we both bring into the collaboration well beyond the sum total of the parts - to birth a new baby neither of us could claim single parentage of.
I don't think so, in so far as I always aspired to play the way I do now but just couldn't get the sounds out always due to technical limitations - now I can pretty much play what I hear in realtime.
I have no doubt that there are great people about though... the thing of it is, nothing to this day moves me like classical music (Debussy, Vaughn Williams).
Maybe its a case of one guitar feeling a certain way to the hands that makes one subsequently move differently over the strings, but my intent is always to wring the maximum emotional resonance out of the object in hand.
