The young players in Mipso bring so many influences into the mix that this is not your average string band. Modern pop sounds are merged with traditional bluegrass and amazing harmonies. The resulting textures are so attractive that Mipso's second album, "Old Time Reverie," debuted at #1 on the Billboard Bluegrass chart last year. Formed in Chapel Hill, North Carolina, Mipso is Jacob Sharp, Joseph Terrell, Wood Robinson and Libby Rodenbough. They played the Matthews Opera House in Spearfish in April.
