Here it is, finally. That bit in previously revealed trailer that made us jump up with surprise. The wub-wub track is posted online. Entitled Unsustainable, dubstep-influenced song was made available to fans who pre-ordered upcoming Muse album The 2nd Law. You can hear the song and watch accompanying visuals above.

Meanwhile, Muse prepare for Olympic Games closing ceremony which is taking place this Sunday, August 12. The band posted a photo from rehearsals on their Twitter account last night.

The 2nd Law is due out on October 1. The first official single off the album is Madness, to be released worldwide on August 20.
