Johannes Brahms was thirty-one when his mother died. As he reflected on his own emotional state, he decided to honor her in music. Realizing that the traditional Latin text for the Requiem focused mainly on the departed, he wondered about those left behind. And so he wrote a work (using German biblical texts) intended to give comfort to the living. On Sunday, April 14, at 4 p.m., guest conductor Dante Anzolini leads the Santa Fe Symphony and Chorus (augmented by the Eastern New Mexico Chamber Choir), with vocal soloists Devon Guthrie and Adrian Smith in Brahms’ gentle, masterful German Requiem. The concert at the Lensic Performing Arts Center (211 W. San Francisco St.) opens with Mozart’s sunny Symphony No. 29. Tickets ($22-$80) are available at 505-983-3530 and santafesymphony.org.
