Over four evenings in Denver, Railroad Earth performed eight sets of music with multiple guest players during its holiday run. Originally the group was slated for three nights at the Ogden Theater but added one final gig on January 1 with Elephant Revival opening the night. Elephant Revival’s Bridget Law joined RRE for portions of the second set that evening, along with fellow violinist Adam Galblum (WhiteWater Ramble) on “Little Bit O’ Me,” “Jerusalem Ridge” and the “Genesis” encore. Elephant Revival also opened on the 29th when Law, bandmate Bonnie Paine and Greensky Bluegrass’ Anders Beck joined in during “Donkey for Sale.” Then Beck’s fellow Greensky Bluegrass members Paul Hoffman, Mike Bont and Dave Bruzza appeared for “Sittin’ on Top of the World.” The 30th saw Sheryl Renee contributing guest vocals to “Mighty River,” “Peace on Earth,” “Hard Livin’” and “Long Way To Go,” while Galblum added violin to “Reuben’s Train.” As for New Year’s Eve, Great American Taxi opened the night and after GAT brought out Railroad Earth’s Tim Carbone for “Reckless Habits,” RRE returned the favor by having Vince “Baby New Year 2011” Herman on vocals and washboard along with Jim Lewin on electric guitar during a run from “Auld Lang Syne” into “Ophelia.” Galblum also returned on the 31 for “Fisherman’s Blues,” while Railroad Earth also debuted a new original song, Todd Sheaffer’s “Judy Judy Judy.”
