Who sings that song on the ipod commercial with the trumpet?

the one with da da da da and its just an outline of people danceing? thanks in advance

That's jazz trumpet player Wynton Marsalis, and his band. It's a song called "Sparks".

I'm pretty sure it was composed specifically for the iTunes advert, so you can download it from there.

You can also check out the advert again on youtube...on the website below (source). Great ad.

I need to find out too, I like that commercial.
