Frank Tichelli is well known for both his choral music and repertoire for instrumental enssembles. Lux Aeterna, a new unaccompanied motet for mixed chorus, is dedicated to the memory of his grandfather. With a lush harmonic language, the lyrical work is true to the meaning of the historic text. The work is appropriate for concert use or in a worship setting with high school, college/ University, or adult voices.
