When not on the road with Umphreys McGee, drummer Kris Myers plays a regular jazz gig in his hometown at Chicagos Webster Wine Bar. As of late, the drummers ensemble has included Brian Dougherty and Vijay Tellis-Nayak, but last week Myers recruited an additional collaborator: Jennifer Hartswick. The singer/brass wonder, who is married to a member of Umphreys McGees road crew and has collaborated with the Chicago jam-titans in a number of settings including Caribbean Holidaze, performed with Myers and his friends throughout their set. Umphreys McGee will begin a multi-night run at Chicagos The Aragon Ballroom on December 29.
