Umphrey’s McGee will release their new album of mashups, Zonkey, on November 11, and one of the tracks on the record will include a special guest in Trey Anastasio Band’s Jennifer Hartswick.

Hartswick lends her vocals to UM’s “Electric Avenue to Hell,” a mashup of “Electric Avenue” and “Highway to Hell” that was debuted during the band’s 2013 Halloween run in Milwaukee. Hartswick recently joined Umphrey’s for the song at their North Coast set in Chicago.
