When Austin's own The Bright Light Social Hour took the stage, the band said it felt like years of effort had finally paid off.
"We've been touring for years and working, so it feels more of just a culmination of hard work and we're just a lot more proud," Curtis Roush said.
But it wasn't their first time on an ACL stage. Back in 2009 the band won a competition to open the festival. We sat down with them at their first ACL, and a lot has changed in four years.
"I don't think I've cut my hair since then," said Jack O’Brien.
They've got longer hair and a lot more experience. The band has racked up critical acclaim, winning numerous Austin Music Awards and closing out Saturday on the Austin Ventures Stage.
"Being home in front of a crowd this large wanting to see a band from Austin -- I mean it's not something I ever really dreamed of," said Edward Braillif.

"First ACL felt like some senior was going to come dump me in a porta potty or something,” Joseph Mirasole said. “Now being at a festival feels kind of like home almost."
More like they’re the senior class now.
"It's just nice to be comfortable here, I mean, I took a nap after our sound check this morning because we went back to my bed. It was awesome," Mirasole said.
