LOS ANGELES – The Dave Matthews Band [ tickets ] has added a pair of new shows to its current tour slate behind the band’s hot-selling new album, “Big Whiskey and the GrooGrux King.” The Sept. 9 and 10 shows at Los Angeles’ Greek Theatre come immediately after the band’s three-night stand at the Gorge Amphitheater in George, WA. The group, which continues the trek tomorrow night (6/19) near Pittsburgh, will head overseas for a European tour leg later this month. Tickets for the two LA shows go on sale to the general public starting Friday (6/ 19). Details for the group’s US tour dates are included below, and international dates are posted at DMB’s website. Last weekend, the band drew more than 50,000 fans to Saratoga Springs, NY, for a pair of outdoor concerts. State-park police made 34 arrests and issued 58 appearance tickets to concertgoers over the weekend, according to local authorities. “Big Whiskey and the GrooGrux King,” which hit stores earlier this month, marks the band’s first studio set since the death of saxophonist LeRoi Moore last summer. Guitarist Tim Reynolds returned to the studio with the band for the record–his first recording with DMB since 1998′s “Before These Crowded Streets.” The set debuted at No. 1 on The Billboard 200 in early June, moving about 424,000 copies during its first week on store shelves to make the album the third-highest selling debut of the year, behind Eminem’s “Relapse” (608,000 copies) and U2′s “No Line on the Horizon” (484,000 copies), according to Nielsen SoundScan retail figures as reported by Billboard. Produced by Rob Cavallo (Green Day, My Chemical Romance), “Big Whiskey” is the follow-up to 2005′s “Stand Up,” the fourth consecutive Dave Matthews Band effort to enter the US album chart at No. 1. In addition to DMB members Dave Matthews (vocals, guitar), Carter Beauford (drums), Stefan Lessard (bass) and Boyd Tinsley (violin), the group will be joined on the road by Reynolds, trumpeter Rashawn Ross and saxophonist Jeff Coffin.
