travel nevada dot com commercial

[songpitch]

it's a commercial for travelnevada.com. there's a freeform vocal (no lyrics that i could discern, just going with a melody/vocal line). err, it's like upbeat vocal improv, over the music, which includes some guitars, but it's not just a vocal over guitar. only thing i could think of is perhaps bobby mcferrin in a collaboration...

any ideas? anyone seen this commercial? i wonder how widespread its airings are...



thanks for any help.
