Umphrey’s McGee performed four shows in three days at South Burlington, VT’s Higher Ground this past weekend, including a special Stew Art Series improvisational gig. A number of Burlington musicians also took the stage with the band throughout the multi-night run. On Friday, Mike Gordon swapped in for Umphrey’s McGee bassist Ryan Stasik for a 16-plus minute version of “In the Kitchen.” The sit-in marked the first time a member of Phish has performed with the band. The following night the group brought out a horn section consisting of Dave Grippo, Bryan McNamara and Jen Hartswick. The three appeared for a rearranged “Cemetery Walk” and Michael Jackson’s “Don’t Stop ‘til You Get Enough” at the start of its second set and, later, “Baby Honey Sugar Darlin‘” and “Partyin’ Peeps.” “Baby Honey Sugar Darlin‘” has not been played live by the band in nine years. Hartswick, who is married to a member of the band’s road crew, also supplied vocals on a show-closing cover of Heart’s “Barracuda.”
