It regularly hosts touring opera and ballet companies including the Kirov, Bolshoi, and the La Scala companies. In addition, the Met has presented recitals by Vladimir Horowitz, Renée Fleming, Kathleen Battle and others. Philip Glass's "Einstein on the Beach" was staged independently at the Met in 1976.
