Neil admitted he fell far short and took lessens from masters. He was impressed with Steve Smiths abilities, which is definitely no knock on Steve Smith. I think it says volumes about Neil. Most would have just shaken it off Neil, restructured, relearned, and though eventually went back to his old style of traditional grip, still took away plenty.
I wish I was a better jazz drummer. Actually, I wish I could play anything resembling traditional jazz. If I ever get to take lessons (never have), I'll take jazz drumming 101 for old boneheads! That should start me with a walk around show and tell of what a jazz kit looks like!
