I knew Diorio's playing - a little - from the inside out, so to speak, as I studied his book Intervallic Designs. My introduction to musodom. IIRC that had a 7inch of him playing. Only found out in the CD epoch that he recorded. I think he's on quite a few though - not as many as Tal Farlow, Allen... I find his stuff clever but cold. That's just me: I don't much like listening to guitar playing, even though, or maybe because, I used to play it. Not as well as Joe, possibly.
