After a cold and tempestuous weekend, we teeter on the brink of full-on summer temperatures. Join me, then, on this rare spring afternoon for pastoral music by Lars-Erik Larsson, love madrigals by Claudio Monteverdi, some adorable musical menageries courtesy of John Lanchbery and Leos Janacek, and a nod to “The Bohemian Girl” by Michael Balfe. The music will be as good as spring itself, from 4 to 7 p.m. EDT, on WWFM – The Classical Network and wwfm.org.
