I've been playing an Alan Hovhaness channel on Pandora for the past couple of weeks and I'm absolutely gobsmacked at the wealth of really terrific music he wrote. I knew he was prolific -- 60 symphonies, a hundred concertos, dozens of oratorios and chamber pieces -- but I was only familiar with his most famous pieces (Mysterious Mountain, And God Created Great Whales, etc.). Turns out there is treasure after treasure in his oeuvre. Really wonderful stuff.
