Tweedy is an American rock band composed of Jeff Tweedy, from the group Wilco, and his son, Spencer. The duo has released one album, Sukierae, in 2014. The elder Tweedy had planned Sukierae to be a solo record, but kept Spencer involved after playing together on early sessions. The group's album name references Susie, Jeff's wife and Spencer's mother, who was diagnosed with cancer during the composition process. When touring, as of 2014 the group included bassist , guitarist , keyboardist-guitarist (Cunningham), and sometimes singer Sima Cunningham (Liam's sister).
