Wilco's Jeff Tweedy and his son Spencer are Tweedy. Tweedy by name, tweedy by nature? That doesn't make much sense, but what does make sense is their musical union. It's not exactly earth-shattering, but like much of Jeff's output over the years, it's about the "song" rather than smashing through any walls.

Last night they teamed up with Holly Laessig and Jess Wolfe of Lucius for a solid performance of 'High As Hello' on The Tonight Show Starring Jimmy Fallon. Watch that below and make sure you pick up their debut album, Sukierae, when it's released on September 16th via Jeff's dBpm label.
