Anyone who has witnessed the Dave Matthews Band knows that lead guitarist Tim Reynolds is a super player who can traverse genre as easily as skimming a rock on a pond. His TR3 trio kicks serious ass. The Watch It album comes out January 19, a week before the tour starts in Newton at The Newton Theatre. Dude’s been at it for four decades. Drummer Dan Martier and bassist Mick Vaugn stick to him like a second skin. Expect funk, jazz and rock in a variety of contexts.
