JOSHUA McGUIRE has written librettos for The Secret of Luca, (based on the novel by Ignazio Silone) and Roscoe (based on the novel by Pulitzer Prize winner William Kennedy) with music by Evan Mack. In October 2016, Roscoe received a full performance by the Albany Symphony featuring soprano Deborah Voigt in the lead role of Veronica. His collaboration with Mack also produced Lucinda y Las Flores de la Nochebuena, a children's opera commissioned by the Fresno State Opera Theatre. Since premiering in 2016, the opera has played for over 25,000 children, including annual performances by the San Francisco Opera Guild. Mack & McGuire’s one-act opera The Ghosts of Gatsby, based on the life of Zelda Fitzgerald, won the the National Opera Association’s 2019 Dominick Argento Prize for contemporary opera, with subsequent productions by Baldwin-Wallace Conservatory and Opera Las Vegas, among others.

Yeltsin in Texas! — a comedy about the fall of the U.S.S.R. commissioned and premiered by Opera in the Heights and Texas Christian University in February 2020 — is currently being expanded and developed into a full-length musical theatre piece with The Blueprint Project. McGuire is currently developing A Nearer Mother with Evan Mack (based on the life of AIDS activist Ruth Coker Burks), as well as a multimedia opera entitled Siddhartha (after the novel by Hermann Hesse) with composer Murray Hidary.

In 2015, McGuire was commissioned to write a libretto for Washington National Opera's American Opera Initiative, and the resulting one-act opera, Alexandra, with music by David Clay Mettens, was premiered at the Kennedy Center. He is also the author of The Secret of Music: a look at the listening life, a book of essays on music and mindfulness. McGuire is the recipient of fellowships from Yaddo, Opera America, and the the American Center for New Works Development. 

McGuire currently teaches at Vanderbilt University's Blair School of Music. He studied at the University of Cincinnati College-Conservatory of Music, where he pursued Master’s work in both guitar and orchestral conducting, holding assistantships in both areas. As an undergraduate at Vanderbilt University, he took the Bachelor of Music summa cum laude as well as High Honors in English Literature for his thesis on musical structures in the work of James Joyce. He currently resides in Nashville with his wife, pianist and conductor Jennifer McGuire, their son Thomas, and a basset hound.
