The Mayor's Office of Special Events has announced some of the highlights of this summer's Chicago Jazz Festival, which runs from August 28 to 31. It's the fest's 30th year, and to acknowledge this milestone the Jazz Institute of Chicago seems to be trying to book an extra-special lineup. Saxophonists Sonny Rollins (pictured) and Ornette Coleman, arguably the two greatest living artists who were active in the bebop era, are among the headliners, and Chicago's own Edward Wilkerson Jr. will be the artist in residence. Additionally pianist Vijay Iyer, trumpeter Dave Douglas, arranger and pianist Gerald Wilson, and Chicago trombonist T.S. Galloway (who's currently based in Amsterdam) have been commissioned to write new pieces for the festival.
