Breaking Atoms

Breaking Atoms is the debut album of American/Canadian Hip-Hop group Main Source. The album was released July 23, 1991, on Wild Pitch Records. Production was handled by the group, primarily by member Large Professor. Recorded during the golden age of Hip-Hop, Breaking Atoms is distinguished stylistically by its incorporation of Jazz and Soul music samples. The album has been highly regarded by music writers due mostly to its production, whose heavy and original use of sampling influenced Hip-Hop producers for a considerable portion of the 1990s.
