Bassekou Kouyate & Ngoni Ba
6:30 p.m. at Millennium Park; free
Rebel ngoni (goat-skin sheathed string instrument) player Bassekou Kouyate is a Mali Afro-pop musician who kind of did to his country's music what Dylan did to folk with the electric guitar; he was the first ngoni player to stand up and string the instrument over his shoulder. At this free show, he'll unleash a set of his award-winning, disco-threaded tribal blues before enlisting some old Howlin' Wolf backing band musicians (Otis Taylor, Eddie Shaw and Hubert Sumlin) for a flashback jam session.

Sketchbook Festival

Sketchbook: dedicated to putting the 500-channels-of-cable experience on stage since 2001.

A different experience is just a blink away. Tonight's preview performance features nine 10-minute plays by Chloe Johnston, Andy Grigg and others. The fest runs through June 27.

Day Games and Heartbreaks

Summer is here, the lights at Wrigley are kindling, and the Red Line is filling up with suburbanites who don't know how to ride trains.

Performing at Pub Theater at Fizz Bar & Grill, where a sorrows-drowning brew is never more than a few feet away.
