I have the pleasure of attending a "Master's session" with TE at the Auditorium in Singapore, it was a 2 hours session where he'd just jams and teaches his techniques. It was amazing. One of my buddy got TE autograph on his guitar too, pretty cool. Pretty down to earth guy too, met him at a bar later, funny guy.
Edit:... hmm that looks like the auditorium that I went to, I was sitting front row, middle.
