After a 45-minute weather delay, the gates of ACL Fest opened just in time for crowds to start filtering in to the Barton Springs stage for Molly Burch’s swoony noon set. Though the air was dense and wet, the Austin-based singer looked crisp and fresh in all-white, and she and her band delivered a sultry, romantic performance centered on the trials of devotion and desire.

Burch’s deep, smooth vocals came through clearly onstage. She lamented the mistakes she’s made, what went wrong and right, and, more generally, the flaws that come with being human, all while swaying back and forth between microphone and keyboard.

The artist was a lovely, dreamy fit for an early ACL Fest set. And more than anything, the performance was an ideal preview for her just-released new album, “First Flower,” which I am now eager to play on vinyl on a drizzly day as I sip red wine and reflect on relationships past.
