i've been a ginormouse fan of dave's for a couple years now. he's stupendous. at the top of my list of all time greatest musicians. and he's funny as hell, too!
john mayer. he's a cool cat. i respect him, for sure.
check out what he had to say about dave barnes:
http://www.johnmayer.com/blog#9 p.s. Dave Barnes is smart as hell too...he promotes himself, makes his own cd's...BANKS more money than he would if he had to pay a ton of money for others to promote him. His music speaks for itself! Word of Mouth..and now John Mayer is giving him props!!
