Umphrey’s McGee have revealed that jazz saxophonist Joshua Redman and New Orleans funk masters Dumpstaphunk will join them at the Fillmore Auditorium in Denver on the second night of their New Year’s run on December 29. The band made the announcement today via their Twitter account, where they also unveiled the art that can be seen above.

As previously reported, Umphrey’s McGee will be throwing down at the Fillmore Auditorium on December 28, 29 and 31. Fellow jambands The String Cheese Incident and Yonder Mountain String Band have also announced New Year’s runs in nearby Broomfield and Boulder, CO, respectively. None of these acts have scheduled performances for December 30, which has fueled speculation about what their plans are for that night.
