Steriogram are a bunch of goofballs who make some pretty good rock and roll music. They haven't had too many hits - this was their biggest one. Thanks to Apple. The song is energetic and fun pop/punk music. Here is the commercial, which should give you a good idea as to what the song is all about.
But the video for the song - which is the only knitted video I've ever seen - makes the song all the more interesting.
