Like the group's bestselling debut album, No Boundaries includes transcriptions for five pianos well as duos and trios featuring various combinations of the siblings. The repertoire include Gershwin's Rhapsody in Blue, Stravinsky's The Firebird, and a medley of the "Simple Gifts" sections from Copland's Appalachian Spring and the "Going Home" section from Dvoršk's Ninth Symphony ("From the New World").

The group is made up of five Brown siblings—Desirae, Ryan, Melody, Gregory, and Deondra—all of whom attended the Juilliard School. Their eponymous debut spent much of 2005 at or near the top of the Billboard classical chart, and re-entered the chart briefly last month.
