For some Austin City Limits Music Festival-goers, disappointment lingers over the cancellation of headliner Childish Gambino, but before the gates opened promptly at 11 a.m. Sunday, we spotted several fans in line sporting the gear of his replacement, rapper Travis Scott. Scott's new album, "Astroworld," topped the Billboard 200 chart when it was released in August, and residual buzz about the release has been thunderous. Scott appeared on "Saturday Night Live" this week where he joined host Awkwafina and cast members in a skit and brought John Mayer and Tame Impala on stage during his live performances.

The weather report for the final day of weekend one of the festival is a mixed bag for fest-goers. The good news is the high is only supposed to hit 86 degrees. The bad news? There's a 50 percent chance of thunderstorms.

In addition to Scott, highlights on the Sunday ACL Fest roster include pop provocateur Janelle Monae and pop star Camila Cabello, whose hit single "Havana" was the song of the summer.
