Heat

The commercial starts with a concert, it is a very fast, "alternative" band. The lyrics are something like: "I'm so tired I think I'm going crazy..."

Then it pans to the crowd where everybody is really muddy, and this kid realizes that his father is standing next to him (dancing along to the music). The father says something about going to look for the mother, he had lost her in the mosh pit.

What is the band and the song?

Well all I know is the banner in the commercial says MXPX.

Heat

MXPX would be the band.

Any ideas on the song?

I had the title, but I forgot it.

It doesn't matter: the song is unreleased, and probably will remain unreleased.

Actually, i think the song will be on their new album in June (or july).
