I recently attended a brass masterclass where the teacher asked the students how many of them were familiar with William Preucil. I was horrified when only two hands went up and one of them was mine.
Preucil has been the concertmaster of the Cleveland Orchestra since 1989 and has a long resume as both a soloist and chamber musician. He is the highest paid concertmaster in the world. Listen to this clip and you will see why. He sure makes that thing look easy to play.
This is a clip of him performing the Beethoven Violin Sonata in A Minor, Opus 23, at the Brevard Music Center on July 5, 2010. He is accompanied by Bruce Murray on piano.
