Praised by Opera News for his “appealingly suave baritone” and the New York Times for a voice that “travels expertly from airy falsetto to basso profundo depths,” Phillip K. Bullock  has been featured in operas, recitals, and concerts throughout the United States and Europe. In the 2024–2025 season, Bullock returns to Virginia Opera, where he showcases his facility with new music, singing Theoliver “Jake” Jeter in the world premiere of Damien Geter's Loving vs. Virginia. He also continues as a Resident Singer with American Opera Project’s Composers and the Voice 2023–2025 cycle, led by Artistic Director Steven Osgood. The 2023–2024 season included a debut with PEAK Performances as Derrick Wheatt in Blind Injustice, as well as a debut with the Eugene Concert Choir and Orchestra, in which he sang the baritone solos in Carmina Burana and Mendelssohn’s 
Die erste Walpurgis Night. 

In recent seasons, Bullock appeared as Zodzetrick in Damien Sneed’s reimagining of Scott Joplin’s Treemonisha with Opera Theatre of Saint Louis and created the role of God of Love in Long Beach Opera’s 2023 world premiere production of The Romance of the Rose, composed by Pulitzer Prize-finalist Kate Soper. During the summer of 2022, Bullock joined Cincinnati Opera to sing the roles of Cato and Watchman in the world premiere of Gregory Spears and Tracy K. Smith’s critically acclaimed opera, Castor and Patience, which was voted the Best New Opera of 2022 by The New York Times.
