How can music be happy and sad at the same time? Listen to Olafur Arnalds and you'll hear it. Depending on your mood, the tone changes, and a song that may have been uplifting one day sounds like an elegy the next. It's spacious, undeniably beautiful work. Much of the music performed in this concert, recorded on April 18 at (Le) Poisson Rouge in New York City, is drawn from the Icelandic musician's recent album For Now I Am Winter.
