Emo quartet Tokio Hotel emerged as one of the most successful new German acts of their generation, scoring three number one singles via 2005's debut LP, Schrei. Bill and Tom Kaulitz, 12-year-old twins, formed the group in their native Magdeburg in 2001, recruiting drummer Gustav Schäfer and bassist Georg Listing to round out the lineup. Originally dubbed Devilish, the teen foursome toured aggressively before signing to Universal in 2003, adopting the moniker Tokio Hotel in tandem with the deal. Teenage girls quickly embraced the band with puppy-love fervor, fueling the group's success in both Europe and the United States. ~ Jason Ankeny
