Criterion Collection commercial with cello music

As many of you know, the Criterion Collection commercials on Hulu have great music!

There’s one commercial that has cello music in the background. Does anyone know what that music is? (I’m not thinking of the commercial that has The Aquarium, from Carnival of the Animals.)

Do you guys know what the cello music is? Given the wide range of amazing things people seem to know around here, I thought the SDMB would be the place to go for this kind of question.

Oh, and there’s a commercial with great bluegrass music. If anyone knows that song, I’d love to know what that is, too.

I don’t know, but would be interested in hearing as well.

Those commercials are amazing. They’re like “magic of cinema” concentrate.
