John Marvin has pursued professional work in both music and the mathematical sciences and for most of his life has been active in both careers at the same time. During his ten years at The Evergreen State College he began to attract the attention of important professional performers. Among them were Julie Ann Giacobassi of the San Francisco Symphony, who premiered his Five Pieces for English Horn and Piano and who persuaded her colleagues in the symphony to premiere his Octet for Winds, and Carolyn Hove of the Los Angeles Philharmonic, who recorded the Five Pieces. His Music from the Night, for two oboes and English horn, was commissioned by Ms. Giacobassi and Zach Hall and premiered at Davies Symphony Hall in April 2000; Giacobassi has recorded this work and the Five Pieces on the Fish Creek Music label. Vocal music by John Marvin includes Journeys, for soprano, horn and piano (to texts by Walt Whitman), Ophélie, for soprano solo, choir and piano (text by Rimbaud), and Ophelia is Mad, based on Hamlet, Act IV Scene 5, for soprano and pre-recorded accompaniment. In 2002 clarinetist Frank Renk and the Wind Ensemble of the California State University Stanislaus premiered his Triptych, for solo clarinet, winds and percussion, and his new work, Tapestry, was performed in March 2004 at Davies Hall, San Francisco. Marvin’s Quintet for Woodwinds, completed August 2003, is dedicated to and commissioned by the Blair Woodwind Quintet—it was premiered at Vanderbilt University, November 2003. He was the guest composer for the Composers’ Showcase 2005 at the University of Montana at which his new work, Three Songs for Soprano and Orchestra, was premiered with pre-recorded accompaniment.
