For their Red Rocks finale, Umphrey’s McGee welcomed out special guest and frequent collaborator Jen Hartswick for a special cover of Rush’s “Red Barchetta” for the very first time. 

Hartswick, who was on her way back from a performance at High Sierra Music Festival with Trey Anastasio Band, took the lead vocals on the Moving Pictures tune and also stayed out for the set closer, “Electric Avenue to Hell” as she took the lead on the AC/DC portion of that mashup which ultimately appeared on the band’s mashup album ZONKEY.
