They found each other at a summer music festival six years ago. They've been making beautiful music ever since.

New York-based pianist Cullen Bryan and violinist Jeri Jorgensen take a Colorado College stage on Sunday for a fifth consecutive year. Well know to local music lovers for her work with the Da Vinci Quartet, Jorgensen says her duo partner can virtually read her mind in the heat of performance.

"Cullan possesses the essential quality that makes a chamber musician great: the ability to anticipate and complement what the other person is going to do. Sometimes he knows how I'm going to play something before I know myself, just from the sound. The music-making becomes spontaneous rather than pre-planned. Every performance is an adventure."

That comes in handy with Bartok's 1st Sonata, which Jorgensen describes as an "epic journey. It's not like his other, more concentrated violin sonatas. It's big. The instruments don't share material. It's like playing two separate but complementary pieces."

In fact, the entire concert is big. It includes two pieces each by Beethoven ("Sonata Op. 30, No. 1" and "Variations Op. 107, No. 7") and Jan?ek ("Violin Sonata" and "Dumka") - all for violin and piano.
