* Colby College Chorale will perform their program “Old Chestnuts, New Fire,” at 7:30 p.m. tonight at Lorimer Chapel.

Just returned from their eighth international concert tour (this time to Seville, Granada, Cordoba, and the Costa del Sol), the Colby College Chorale explores old and new music that reflects the rich ecclesiastical tradition and centuries-old multi-ethnic culture of Spain’s southern region and that delves into Spanish and American folk traditions. Among the music you’ll hear are works for sacred services by Rossini, Poulenc and Mendelssohn; a new piece commissioned by and composed for the Colby Chorale by the young American composer Ryan Vigil; Spanish love songs; Argentine dances; and African-American spirituals. Join us for a wealth of choral music — an evening of old chestnuts and new fire. Directed by Paul Machlin.

* “Not a Silent Generation: Post-War American Jews and the Memory of the Holocaust” will be at 5 p.m. Tuesday, at the Pugh Center, Cotter Union

In the years immediately following World War II, American Jews, through their communal institutions, created a memorial culture that hallowed the memory of the six million Jews who perished in the Holocaust. Text by text, artifact by artifact, and act by act, they experimented with words and deeds to both remember those ruthlessly killed and to effect changes in the Jewish world and in America. Rather than avoiding the catastrophe, as many historians have asserted, American Jews considered themselves obliged to remember and to tell themselves, their children and the larger American world what had happened.

* A talk, “Human Rights in China,” is set for 4 p.m., Tuesday in Room 215, Lovejoy Building.

Dr. Li Xiaorong, a prominent Chinese human rights activist, is founder and director of an international human rights group with extensive networks in China. She was the first executive director of Human Rights in China, a U.S.-based human rights group, and also served on its board until 2005. Her research projects have won support from the National Endowment for the Humanities, the MacArthur Foundation, and the U.S. Institute of Peace. On her last trip to China to visit her family and conduct research, she was arrested, searched, interrogated, and expelled from the country.
