Multiple reports on social media indicate that people in ACL T-shirts are spinning signs around town (you know, the kind that tax preparation services use) bearing the names of music acts. No other context. Just names.

Chris Stapleton is probably going to be at ACL and I'm stoked

99% sure Chainsmokers are going to be at ACL after seeing a guy in an ACL shirt spinning a sign with their name on it.

Our music writers have fantasy picks for the ACL lineup�(including one big prediction for Radiohead). But we�ll know for sure if LCD Soundsystem, Haim and more are really on the lineup before you know it. Readers: Have you seen any other sign-spinners in Austin today?

And in preparation for the fest, cross your fingers that vets Asleep At the Wheel will keep their long streak of ACL performances alive. A safe bet if there ever was one.
