Forget Memorial Day — the first Blues on the Green lineup just dropped, so we can declare summer officially here. Austin's free annual concert series returns to Zilker Park for another year of live music on the Great Lawn.

Blues on the Green is now presented by the newly minted ACL Radio, which took over KGSR in September 2018 and moved the station to 97.1. Despite the change, the format for Blues on the Green remains the same. First, grab your blanket and picnic basket, and then join friends, family, and dogs for an evening of free jams.

The season's first show is slated for May 22, with Jamestown Revival and Sir Woman, according to the ACL Radio website. Music begins at 8 pm and runs until about 10 pm. In case of rain, the show will be held on June 5.

Additional summer 2019 dates are June 12 (rain date June 19), July 17 (rain date July 24), and August 7 (rain date August 14), according to the City of Austin. Per usual, bands for the remaining three shows will be announced as summer rolls along.

Considering Blues on the Green does occur in the heart of Austin, the city suggests walking, biking, or taking CapMetro rather than driving. (And forget about parking in the nearby neighborhoods.) CapMetro's trip planner can be found here.
