Mystery Monday third anniversary at El Mercado. A successor to singer-songwriter Sarah Elizabeth Campbell’s long-running “Bummer Night” series, Mystery Monday started up in November 2012 with Campbell and Christine Albert as co-hosts. Campbell died in December 2013, but Albert has kept the event rolling, gradually growing its audience until El Mercado added a great new stage and sound system to its back room. They’ll celebrate with a special program that celebrates Campbell’s life and music, featuring Albert and co-hosts David Carroll and Bill Kirchen plus many special guests, including Bobby Kallus, Kym Warner, Chris Gage, Jimmy LaFave, Marcia Ball, Rich Brotherton, Judy Painter and Rose Kimball. Free. 7:30 p.m. 1302 S. First St. mysterymondayaustin.com.
