Wolfgang Amadeus Mozart Clarinet Concerto in A major: Superb!

[Windsong]

The Iceland Symphony Orchestra performs a fantastic concerto here.  Notice how she adjusts her reed, midway.  It was as close to flawless as any performance has a need to be, and what a lovely piece of music.  The level of skill involved here - not just in mastery of her instrument - but also in flawless memorization is just astounding to me.  I am not a classical player, but I have a great love for the music. 

This piece was released in 1791.  Imagine the struggles on a period correct 6 key Stadler Basset clarinet.   I can only imagine the fingering challenges.  They say this was Mozart's last great work:
