Bang is the sixteenth overall and eleventh North American album by the a cappella group Rockapella. It is the first studio album the group has released since 2002, and marks the first recording appearance of members John K. Brown and Steven Dorian, who had joined the group in 2004 and 2010. The album consists entirely of original music, making it the second all-original album released by the group, preceded only by their 1994 Japanese release Vocobeat, and is also the first Rockapella album to have at least one song written by each of the five members. The album contains a special bonus fourteenth track: a cover of Vampire Weekend's "A-Punk."
