Dirk Nowitzki Goes Nuts on the Tambo at Avett Brothers Show Now that the Mavericks are out of the playoffs, superhuman fadeaway-shooting 7-footer Dirk Nowitzki can sit back, root for the Spurs and catch his favorite bands live. At Sunday night’s Avett Brothers show in Grand Prairie, Texas, the folk-rockers invited Nowitzki to join them onstage, where he took a tambourine and … just … No words. He looks twice as excited onstage than he did winning the NBA Finals last year. Had a blast at the avett bros concert. Great show. Great band. — Dirk Nowitzki (@swish41) June 3, 2012 [Cosby Sweaters; main image Keith Allison] Follow us! Click and Follow Us for more updates straight to your news and nonsense feeds.
