Green Mill All-Stars

The Green Mill All Stars were formed for the purpose of performing new music at the Green Mill for the fall concert, part of a series of three new music concerts at the club that are presented each year. The founder of the series, composer George Flynn, began it with a January concert that would always include a celebration for his birthday, done with humor and often with audience involvement. The new music concerts are now scheduled three times a year: fall, winter, and spring, and the curators are usually members of New Music Chicago or Chicago composers and performers of new music. The fall concerts have been curated by Frank Abbinanti and Jeff Kowalkowski, and since 2023 have been curated by Janice Misurell-Mitchell. Recent programming has included a wide range of music from the 20th and 21st centuries: new instrumental and electronic music, jazz, vocal and spoken word pieces, and a few that include audience participation.

The fall concert repertoire is created with particular themes in mind. These may be related to musical traditions, political ideas, or general repertoire that relates loosely to the concert's title. An example is the satiric "The Good, the Bad and the Ugly" concert, which brought in 100 people.

The concert venue provides a welcoming space for musical risk-taking, humor, and pieces that may fit more into performance art than traditional new music concerts. The casual nature of the concerts creates an atmosphere of music which challenges its listeners yet makes them feel included in the musical space.
