NEW YORK - The chemistry is over: rock outfit My Chemical Romance has disbanded. The New Jersey-based band announced Saturday that "it has come time for it to end." The foursome thanked fans in a statement. My Chemical Romance's sound is a mix of alternative, punk rock and pop. Band members released their debut album in 2002 but really made a splash on the music scene in 2004 with the platinum-selling "Three Cheers for Sweet Revenge."
