On Sunday, November 6 at 3pm Milton Community Concerts will present the compositions of local composer Carol Koffinke in a program for choir and professional soloists. This concert, “Sharing Ourselves, Reuniting Our Voices: Music by Carol Koffinke”, will take place in the historic Meetinghouse at First Parish of Milton, 535 Canton Avenue, and will feature several world premiere performances.

Soloists will be Angela Yam, soprano; Alexandra Dietrich, mezzo-soprano; David Rivera Bozon, tenor; and Keith Eric Brinkley, baritone. The choir is made up of singers from the First Parish Meetinghouse choir, the UCC Norwell choir, and others from choirs around the South Shore.

Composer Carol Koffinke began as a writer of poems, plays, and books, several of which were performed and published. Since then she has set many of her poems to music in original settings for solo voice and for choir. Highlighting this program will be the world premiere of “Life”, a work for four soloists, choir, and piano which explores in four distinct phases our universal life journey.
