Talk about Suddenly. These four kids from San Diego (vocalist Zachary Porter, guitarist Nathan Darmody, bassist Cameron Quiseng and drummer Michael Martinez) got together in 2007, when they were all still in high school, and wrote their first songs (like hit single "A Different Side of Me") in each other's bedrooms. By 2008, those songs (which the boys had posted on the band's MySpace page) had earned them the attention of Disney, which signed them to Hollywood Records and promoted them all over Radio Disney. And by 2010, their appropriately titled debut had dropped. Of course, it wasn't all speed and serendipity: The band's hard work (including tireless gigging, YouTube promotion, even passing out flyers outside Jonas Brothers shows) is what made everything come together for them so Suddenly.
