Free shows at Auditorium Shores are a longstanding SXSW tradition. Further announcements are expected in the next few days about possible free shows Thursday and Friday, March 14-15.

Badges aren't required to attend, but it's necessary to sign up at the SXSW website for a SXSW Guest Pass, which is free. It's also good for admission to a handful of other specially designated events.

Andrews' 2018 release, "May Your Kindness Remain," landed on several year-end top-10 lists and earned her an Emerging Artist of the Year nomination at the Americana Music Awards.
