One of Brookline High’s liveliest musical traditions, the Spring Music Festival brings together for two nights all the school’s faculty-instructed music ensembles: Concert Choir, A cappella Choir, Camerata, Concert Band, Jazz Band, and Orchestra. Each night offers a different program, with music ranging from classical favorites to today’s hits. A highlight of the Wednesday concert will be the premiere of “Moliendo Café,” a combined work for all three choirs, both bands, and orchestra (that’s 250 singers and instrumentalists!) specially arranged and composed for the occasion by Venezuelan composer Luis Pérez. Festival repertoire also includes music by Bartok, Earth Wind & Fire, and the Lion King, plus tangos and more.
