The Boston Phoenix praised baritone Emery Stephens for singing "with ringing suavity and articulate intelligence." His performances include collaborations with the Boston Art Song Society, Bridge Chamber Music Festival, Handel & Haydn Society, Abridged Opera of Ontario, Wilmington Symphony, Arbor Opera Theater, Michigan Philharmonic, Ann Arbor Symphony, Boston Lyric Opera, Opera New England, and Carolina Ballet, as well as the North Carolina Symphony. He participated in a revival of Dave Brubeck's 1969 cantata, The Gates of Justice, written in response to the assassination of Dr. Martin Luther King Jr., sponsored by the Detroit Jazz Festival Community Series, "Jazz Speaks for Life," alongside Detroit Brass and Percussion Ensemble, Detroit Choral Society, Wayne State University ensembles, jazz pianist Jason Moran and his trio, The Bandwagon, to commemorate the 50th anniversary of the Civil Rights Act.

In the blues opera De Organizer, which features music by James P. Johnson and lyrics by Langston Hughes, he sang Brother Dosher for a Naxos Music recording. He also performed works by contemporary American composers, including the world premiere of JFK: The Voice of Peace by Dan Welcher, The Passion of John Brown by Jesse Ayers, Paddle to the Sea by Andre Meyers, Sweet Music in Harlem (world premiere) by Andy Kirschner, and True Witness: A Civil Rights Cantata by Jodi Goble. 

The Boston Globe wrote that "As Mel in Michael Tippett's opera, The Knot Garden, Stephens disappeared entirely into his character. As a singing actor, he worked with notable directors such as Elkhanah Pulitzer and Dorothy Danner, as well as choreographer Bill T. Jones. He was a Northeast regional finalist in the Leontyne Price Vocal Arts Competition and sang in masterclasses for international opera professionals Nico Castel and Martina Arroyo. He was also a freelance professional choral member of Boston's Grammy-winning Handel & Haydn Society. He joined the Boston Early Music Festival in Monteverdi's L'Orfeo at Harvard University with conductor Andrew Parrott. 

In addition to guest residencies at colleges and universities across the country, his teaching-artist experience includes community engagement projects with the Handel and Haydn Society, Boston Lyric Opera, and Michigan Opera Theatre (now Detroit Opera). During the summer, he is a core faculty member of the Singing Down the Barriers Institute at the University of Michigan. Dr. Stephens also served as a master teacher for the Hampsong Foundation, an organization founded by baritone Thomas Hampson, which uses American music to engage K-12 students in literature, history, and social studies. His past engagements with the Hampsong Foundation include lecture performances at Carnegie Hall/Weill Music Institute, Fenimore Art Museum in Cooperstown, New York, and the Northwest Museum of Arts and Culture sponsored by the Spokane Symphony.

He has presented his scholarship at meetings for the College Music Society, National Association of Teachers of Singing, the International Congress of Voice Teachers, the International Society for the Scholarship of Teaching and Learning, the Race & Pedagogy Conference, and the African American Art Song Alliance. His research on Black composers' works and their place in the classical canon appears in the Journal of Singing, the Music Teachers National Association Journal, the Scholarship of Multicultural Teaching and Learning, and as a contributor to So You Want to Sing Spirituals by Randye Jones, and as a co-author of Singing Down the Barriers: A Guide to Centering African American Song for Concert Performers with Caroline Helton. He also served as a lecturer, vocal coach, and recital curator for the MN Duo Program at the 2025 Source Song Festival in Minneapolis. 

Dr. Stephens, raised in Boston, earned a B.A. from Gordon College, an M.M. from Boston University, and a D.M.A. from the University of Michigan. He studied vocal techniques with Lisa Popeil and is a member of the National Association of Teachers of Singing and the College Music Society.
