Connor Lidell, baritone, has been a professional musician and teacher of musicians for over a decade. After receiving degrees and certificates from Indiana University’s Jacobs School of Music (Bachelor and Master of Music) and New York University’s Steinhardt School of Culture, Education, and Human Development (Advanced Certificate of Vocal Pedagogy), he moved back to his home state of Texas.

Working as a session singer and freelance performer, Connor has been involved in many unique musical projects. He has given the world premiere of many stage roles, sung alto (yes, alto) on a professional jazz harmony track, sung in a choir at Carnegie Hall, and performed at the Cowboy’s Stadium in Arlington. Some of his most cherished professional roles are Jud Fry (Oklahoma) at Indiana University, Nettuno (Ruggero) with Dell’Arte Opera Ensemble, premiering the role of Stephano (Princess Maleine) also with Dell’Arte, Swallow (Peter Grimes), and Masetto (Don Giovanni) both at Indiana.

Connor grew up in the Texas public school system at James Martin High School in Arlington. He made the prestigious TMEA All-State Mixed Choir three years in a row, and his senior year was first chair in the competitive Bass I category. He also won the NATS Tri-State vocal competition winning against college students in the music theatre category. Though, his favorite accomplishments during his time in Texas are music directing You’re A Good Man, Charlie Brown and performing the role of Sweeney Todd both during his senior year at Martin High School.

Since returning to Texas, Connor has coached multiple students to All-State mixed choir. His students have received professional theater contracts and have been on national tours. He will be teaching at the University of Texas at Arlington in their Musical Theatre department this fall!

He spends his free time jamming on the piano with friends, watching Community on Netflix, and planning elaborate Disney World vacations where he likes to go multiple times a year.
