[3] At the age of 15, funding for music was cut at his school, so he joined the jazz big band at a local university instead; there, he was mentored by bass trombonist and tubaist Bill Lowe.

[6] Continuing his interest in music, Bynum attended Wesleyan University, where he studied with a major influence on his future – Anthony Braxton – as well as with Pheeroan akLaff, Jay Hoggard, and others.

[8] From 2007, Bynum has been part of The Convergence Quartet, with pianist Alexander Hawkins, bassist Dominic Lash, and drummer Harris Eisenstadt; they released their fourth album, Owl Jacket, in 2016.

[14] Bynum expounded on his releasing four recordings of the same piece: "I want to ask listeners to consider the composition as a set of possibilities rather than a fixed document, to encourage them to enjoy the mutable nature of the music in multiple realizations rather than focusing on one particular performance.

"[14] In 2014, he undertook another "Acoustic Bicycle Tour" from Vancouver, Canada down the West Coast to Tijuana, Mexico, captured in a short documentary film by Chris Jonas.

[24][25] A further activity has been organizing music events, including the Sound Genome project in Vancouver in 2010 and a festival at the Roulette club in New York City the following year.

[26] A reviewer of Next commented that Bynum "deploys a litany of buzzes, whistles, drones, pinched fanfares and garrulous brass muttering in acrobatic arcs that twist and somersault.
