Darius Rucker's summer tour has been so successful, he has decided to add another run of dates that will extend into the fall.

More than 400,000 fans have attended Rucker's Southern Style tour since it kicked off in May, according to a press release. Last week the show scored more sellouts in Gilford, N.H., Boston, Mass. and Jones Beach, N.Y., and with 15 dates still left to play, it's on track to sell in excess of 700,000 tickets by the time it wraps up its current leg.

The tour's summer run has featured Brett EldredgeBrothers Osborne and A Thousand Horses as support acts. The latter act will stay on for the upcoming fall shows, with David Nail joining the tour for those dates.

The tour has received critical accolades in addition to its box office success. "Rucker proved to be one to defy expectations, if not challenge conventions,” the Asbury Park Press writes, while the The Record singled out Rucker’s “once-in-a-lifetime voice — burly and richly textured — as well as a vocal delivery that’s warm and ingratiating."

The tour takes its name from Rucker's current single, "Southern Style," which is the title song and second single from his current album. The project's lead single, "Homegrown Honey," reached No. 1. Rucker recently shot a video for "Southern Style" that is directed by Peter Zavadil.

Show dates and ticket information for Rucker's extended fall concerts dates are to be announced.
