@J Moose - STP
Well I have heard plenty of great ones I cant repeat, it must be tough as hell being in that band that's all I can say.
As for Robert, I can say without a doubt he has to be one of most talented and down to earth guys you could imagine. He is from NJ that has something to do with it!
One day he just sat in my office on the couch playing acoustic while we talked back and forth, after 15 minutes or so I was thinking what is he playing? it sounded like the next STP hit, but he tells me was just noodling around and doesn't even know what he played!!
I think I sat the next 20 minutes just as a fan listening to the amazing melodies and chords he played!
