Shady Grove boasts that the weekly spring and summer concerts it throws with radio station KGSR are part of the city's longest-running free live music series. We can't confirm, but we do know that there's no cover charge and all ages are welcome, even with the $4 ZiegenBock on tap. The 2017 season opens with the Charlie Mars Duo on April 13 and wraps with Jimmy LaFave on Sept. 14. In between, James McMurtry, Dale Watson, Bob Schneider, Sarah Jaffe and Rhett Miller, among others, are also booked to perform. Check out the Spotify playlist featuring all the artists on Shady Grove's website so you can sing along in person.
