The Vienna Philharmonic is in a class of its own. Drawn from players in the Vienna State Opera, the orchestra rarely performs concerts. When it does, the finest conductors of the world are on the podium. It is an orchestra steeped in tradition, from the apparel worn to the music-making approach. The Philharmonic is peerless in the operas of Strauss and Wagner, where they bring the most radiance out of every score. They perform mostly in the Musikvereinsaal, which has a mellow acoustic to match the orchestra's sound.
