From 2014's largely under-the-radar "Sukierae" double album: private music nevertheless released for public consumption. Meaning it was made for the sake of making it: always the best reason. (And we now know it didn't completely drain Jeff Tweedy's creative coffers.)
But why are we here? Because Spencer Tweedy demonstrates otherworldly gifts by managing to make something done in 7/4 time sound funky as heck. I can't imagine that's an easy thing to do.
Bonus beats: he can also do it live.
