Dave Matthews Band has announced new dates for its upcoming United States tour.

The tour includes concerts at Fiddler’s Green Amphitheatre in Greenwood Village on Friday, Aug. 23, and Saturday, Aug. 24.

With the summer tour, Dave Matthews Band will be introducing new sustainability measures as part of its “On The Road To Zero Waste” initiative – a partnership with Live Nation.

Dave Matthews Band has sold a collective 38 million CDs and DVDs combined and more than 25 million tickets since inception, making them the second largest ticket-seller in history. The band’s new album, Walk Around The Moon was praised by Pitchfork saying the album’s “tight-knit, tender songs.” Associated Press noted, “‘Walk Around the Moon’ is a varied set, with the tracks veering from small and intimate to brassy and political, with a filthy groove propelling ‘Break Free,’ a nostalgia-tinged and brooding ‘Monsters’ and the band absolutely cooking with ‘The Only Thing.’
