Catching hometown jamgrass legends Yonder Mountain String Band has become a Denver holiday tradition, as the band has performed New Year's Eve concerts here every year for the better part of the last decade.  From electric performances at the Paramount Theater, a supporting/collaborative effort last year with Widespread Panic at the Pepsi Center, to multiple showings at the Fillmore Auditorium the band has routinely and successfully rung in each New Year with the Colorado faithful.
