Dave Matthews Band closed their winter tour at Philadelphia, PA’s Wells Fargo Center on Saturday night. On the second half of their tour, Grammy-nominated roots act The Lumineers opened the show, and a member of Dave Matthews Band joined them onstage for the run’s finale. Dave Matthews Band trumpeter Rashawn Ross—who is also a longtime member of Lettuce—emerged at the start of The Lumineers’ set for a take on “Charlie Boy.”

The Lumineers will close 2012 at Denver, CO’s The Ogden Theatre on December 30 and 31. Recent Relix On the Verge subject Shovels and Rope will open both shows, and Paperbird will also support on December 31.
