The 10,000 Lakes Festival has confirmed some additional artists for its July event, with the Assembly of Dust, RAQ, Papa Mali, and The Breakfast all added to the line-up. In addition, festival organizers have cleared up one ambiguity that has perplexed some would-be concertgoers (this means you ZZYZX), by affirming that Trey Anastasio will indeed join Mike Gordon and the Benevento/Russo Duo for their set. The fourth annual festival, which will take place in Detroit Lakes, MN from July 19-22 also will feature: Phil Lesh & Friends, String Cheese Incident, Keller Williams, Umphrey’s McGee, Medeski, Martin & Wood, Tea Leaf Green, O.A.R. Big Head Todd & The Monsters, Hot Buttered Rum and the Wood Brothers. For more on GRAB, read Mike Greenhaus current interview with Mike Gordon.
