I listened to the whole thing while working this morning. Pretty great interview, touches on John's start as a player, growing up, college, the early DT days, signature guitar stuff, signature amp stuff etc...
A couple interesting things he mentions at the end about what he is up to in the near future - Asia and NA I&W&B tour, his guitar camp in August, and then DT back in the studio early next year.
He does make a couple comments about the next album. He mentions they are working on a signature JP 8 string (there isn't a specific time table in place for it yet) and if it happens to be ready when DT are in the studio again, he wants to take it out of the box, experiment and see what happens to maybe use it on the next record. Basically, exactly what he did when he received his first 7 string during the Awake sessions, he took it out of the box and starting jamming on what would become The Mirror. He also confirmed the next album will not be a concept album (which we all figured) but also made another comment about him and the guys really wanting to do a metal-type, heavy album after TA. I think JR had mentioned this recently as well.
So nothing completely new, but definitely a couple cool confirmations and tidbits. Overall, really good interview. JP also plays throughout just jamming and then breaking down tones on channels of the JP2C and different effects he uses.
