Peter Schmidl (clarinet), Vienna Philharmonic Orchestra, conducted by Leonard Bernstein. Recorded in September 1987 at the Konzerthaus Wien. Wolfgang Amadeus Mozart (1756-1791) wrote his concerto for the clarinetist Anton Stadler, who was a Freemason like Mozart.

Composed two months before Mozart's death, the Concerto K. 622 is Mozart's most important wind concerto and "the" Clarinet Concerto throughout the repertoire.
