Hornist Eric Rusky invokes Roman gods in Library of Congress recital

It's not often that you hear a French horn recital dedicated to one of the Roman gods. But the two-faced Janus (who looks to both the future and the past) turned out to be an apt inspiration for hornist Eric Ruske, whose recital at the Library of Congress on Friday explored the ancient and almost primal sound of the instrument -- by focusing on works from the 20th century.
