Watch Gustavo Dudamel make music on 'Sesame Street' [Video]

What did the conductor say to the Muppet?

Watch below to see Gustavo Dudamel make his musical “Sesame Street” debut.

During the minute-and-a-half segment, which premiered Monday on PBS, the Los Angeles Philharmonic's music director, accompanied by Elmo, demonstrates the meaning of "stupendous" with a violin-playing sheep, an octopus percussionist and an all-penguin choir.

Earlier this week, the Los Angeles Philharmonic announced its 2012-13 season, which includes many Dudamel appearances, including the second of a planned trilogy of Mozart-Da Ponte operas, "The Marriage of Figaro." And while the show may be stupendous, we doubt there will be any penguins.
