I have a jazz background and some of those ideas there are based on Smith's famous solo from Journey's live record called Captured. (Check that out and it will be obvious.) Smith few up a jazz drummer so the genesis comes from that entirely. Then it was up to me to incorporate my ideas in that framework. When you compare the two there are some similarities yet totally different. It honestly was my heartfelt tribute to someone who had meant very much to me.
The whole solo is transcribed in the Methods & Mechanics book, which has all the songs and solos from the first DVD along with a CD of performances and play alongs. Hope it helps!
