the fall of 2017, he was awarded a MacArthur Fellowship for his work in music performance and composition. In 2018, Sorey premiered Cycles of My Being commissioned by Opera Philadelphia, Lyric Opera of Chicago, and Carnegie Hall starring Lawrence Brownlee with poetry by Terrance Hayes. This song cycle centers on what it means to be a Black man living in America today and in 2020 was made into a film with Opera Philadelphia and released on their Digital Channel. In 2018 he also released Pillars on Firehouse 12. The following year he was named Composer in Residence for the Seattle Symphony and Opera Philadelphia, and his duo album with Marilyn Crispell, The Adornment of Time, was released on Pi Recordings. In March 2020, just before the pandemic hit the Northeastern United States in full force, Sorey self-released his sextet's Unfiltered. That fall, he joined the faculty at the University of Pennsylvania as Presidential Assistant Professor of Music. Beginning in 2019, Sorey embarked on several musical projects with Alarm Will Sound including For George Lewis, a through-composed composition scored for sinfonietta commissioned by the ensemble, as well as several versions of autoschediasms, spontaneous compositions led by Sorey drawing on the improvisational abilities of the instrumentalists. For George Lewis was premiered in 2019 at Washington University in St Louis and released on an album with two versions of autoschediasms in 2021. While one autoschediasm came from a live performance in St Louis in 2019, the other was recorded completely remotely with musicians performing from five states during the COVID-19 pandemic. Additionally, Sorey recorded a holiday-themed autoschediasm based on Coventry Carol and Sussex Carol with Alarm Will Sound. In 2022, Sorey’s composition Monochromatic Light (Afterlife), commissioned for the 50th anniversary of the Rothko Chapel premieres there, followed by performances at the Park Avenue Armory in New York.

He opposes the categorization of music by distinct genres, and in interviews and his doctoral thesis has critiqued notions of improvisation and composition as mutually exclusive.
