Featuring a dozen ensembles performing three and a half hours of music almost exclusively by living composers, the event seeks to highlight the work of new and established groups dedicated to new music. Groups like New Score Chamber Orchestra, the Hippocrene Saxophone Ensemble, and UCF Collide Ensemble have been performing in Orlando for half a decade, while others have formed more recently or will make their debut at Marathon AMF.

Composers represented on the program include names like Philip Glass, Steve Reich, Gyorgy Ligeti, and esteemed local composers like Benoit Glazer, Charles Griffin, and David McDonald.

Each group will perform roughly twenty to twenty five minutes of music. Between sets there will be interviews with the artists and other contributors to Orlando's contemporary classical scene, including concert presenters, radio and podcast hosts, and writers. The short sets and Timucua's BYOB/potluck tradition will allow for people to meet, share, and learn about new projects. Stay for the whole day or just a couple of performances.
