Wilco's double-encore super set at Red Butte Gardens in the foothills of the Salt Lake Valley last Monday was a gem of a concert. And I realized something about them for the first time.
Wilco's sound is defined by tension. This tension is most evident in the harsh juxtaposition between Jeff Tweedy's laid-back, mellow voice and Nels Cline's aggressive, attacking guitar. The result is a give-and-take relationship that provides the best of folksy alt-country and face-melting rock—and Wilco manages to cover everything in between.
