Jennifer Hartswick will lead a two-night super jam throwdown at the 1Up Colfax in Denver, CO, in honor of the fifth anniversary of MusicMarauders, a music media outlet. Hartswick, who is perhaps best known for her role as trumpetist and vocalist in the Trey Anastasio Band, has already recruited a number of talented performers, including: Natalie Cressman (TAB), Oteil Burbridge (Allman Brothers Band), Alvin Ford Jr. (Dumpstaphunk), Joey Porter (The Motet) and Skerik. 

The shows will be held on February 13th and 14th, with special guests TBA. Tickets go on sale at noon ET today, 12/22.
