One of the most successful rock bands to have emerged in recent years, 3 Doors Down is considered a phenomenon within the music industry. Often called 3DD, this five-piece outfit came out of small-town Mississippi to become a record-breaking act whose two albums and handful of singles have sold in the millions. The band became the first debut act in the history of the record charts to hit number one concurrently in Modern Rock, Active Rock, Album Rock, and Heritage Rock radio formats. 3DD accomplished this feat with its single "Kryptonite," a track that uses Superman imagery to explore the question of what would happen to someone who, after having been placed on a pedestal, does something to damage his or her image. The group is lauded for bringing melody, hooks, wholesomeness, and a straightforward approach back to rock 'n' roll which, at the time that the group put out its first CD in early 2000, often was considered to be in its dying stages or to have been co-opted by genres such as rap/rock, punk, and heavy metal.
