David Wetherill, long-time first-horn player with the Philadelphia Orchestra, began his professional career as Principal Horn with the renowned opera house, "Teatro alla Scala" in Milan, Italy, playing the greatest operas with the finest singers and conductors in the world.

In 1976, Pierre Boulez asked Mr. Wetherill to come to Paris to work with the "Ensemble InterContemporain," as a founding member of that cutting-edge chamber orchestra. During this period, he performed literally dozens of premieres by the leading contemporary composers of the day, including Berio, Stockhausen, Xenakis, Boulez, and Messiaen.

At the invitation of Maestro Eugene Ormandy, Mr. Wetherill returned to Philadelphia, where he played for nearly 30 years. Now retired from full time performing, he is active with teaching and conducting, and occasionally performing on the horn if the stars line up properly.
