Who doesn't like free outdoor events? Tomorrow, Columbia College puts on their daylong 15 exhibition artwalk and sale called Manifest that celebrates grad students from all of their departments. Music is never afar and Grammy winners Ozomatli (they are good!), hip-hop stud Saul Williams and fronting the jazz beat, Steve Turre take to three stages. Starts at 11am and ends at 9:30pm and, again, admission is free. (Hat tip to Sarah who's got the inside scoop).
