BANGOR — The Bangor Symphony Orchestra’s 2014-15 Masterworks Season will conclude at 3 p.m. Sunday, April 12, at the Collins Center for the Arts with “Serenade to Music,” a program of uplifting and spiritual works by Jennifer Higdon, Ralph Vaughan Williams, Johannes Brahms and Anton Bruckner. Music Director and Conductor Lucas Richman will lead the program, featuring guest vocalists Elisabeth Marshall, Joelle Morris, Francis John Vogt and Aaron Engebreth alongside the University of Maine Singers and Oratorio Society.

The concert will open with Pulitzer Prize-winning composer Jennifer Higdon’s “blue cathedral,” a meditation on life and death that features unusual musical effects to create an atmosphere all its own. The work was premiered in 2000 and is one of the most-performed pieces of contemporary classical music. The famous Haydn Variations by Brahms will follow, before the University of Maine Singers and Oratorio Society take the stage for the second half of the program.

The second half  of the program also will highlight guest vocalists in Vaughan Williams’ “Serenade to Music,” based on text by Shakespeare, and Bruckner’s “Te Deum.”

Soprano Elisabeth Marshall of Portland earned a bchelor’s degree in music education at the University of Southern Maine before going on to the prestigious Jacobs School of Music at Indiana University to earn a doctoral degree.

Tenor Francis John Vogt of Orono is director of choral studies at the University of Maine, and brings to his soloist duties a wealth of experience from his work with festivals and choirs around the United States and in Maine.

Baritone Aaron Engebreth recently was seen with the Boston Modern Orchestra Project, Boston’s Radius Ensemble and in his Carnegie Hall debut. Though he now lives in Minnesota, he previously lived in Portland where he helped found the Florestan Project and regularly returns to the Portland Conservatory of Music for recitals.

“Serenade to Music” is sponsored by Bangor Savings Bank which will provide cookies and coffee to concertgoers at intermission. Jeff Shaw, CPA of H&R Block Ellsworth/MDI, is the guest artist sponsor.
