A shitty, talentless, auto-tuned, sell-out band. They are from Edmonton, Alberta, Canada. They were on a show called disBAND on MuchMusic. After they passed on the show, they were asked to move to Toronto, by MuchMusic and were signed. Their single debuted at #2 on the Canadian Hot 100 based on the large amount of downloads in the first week. They changed their name and their sound, for mainstream fame, but STILL suck. Their fans are all usually fat, unattractive, 13 year-old, scene, bitty girls.
