Just out of curiosity, how many now- signed guitarists were over 20 before they picked up a guitar? I know of a lot of players who got into bands and put out material after 20, but they always seemed to have picked up the guitar in their early-mid teens...
I am....making progress...
mm, you may get a better response in a different forum

but Jonathan Coulton is one
I'm pretty sure Kings Of Leon were in there 20's before they even heard rock music.
wasnt the guy from boston old(er) before he started playing guitar? I totally forgot his name somehow :P
