Definitely check out Capital Road. They're a Pittsburgh band but have a great sound!!
They take their influence from bands like Dispatch, and O.A.R
maybe some 80s hardcore bands like Bad Brains, 7 Seconds, Youth Brigade. Tiger Army. The Dickies. Echo and the Bunnymen. Joy Division.
Dillinger Four are good. The Black Keys are good. Me First and the Gimmie Gimmies are ok for a laugh.
Charlie Parker and The Stooges were good suggestions
