March Bandness is a marketing tool employed by radio stations across the United States to promote listener interaction. There is no specific format other than it pits 64 recording artists against each other in the same style as the NCAA Tournament.
The choice of the bands may be arbitrary, or it could use a seeding system based on popularity with listeners, chart hits or a number of other parameters.
Those rewarded in the process may also differ. In some cases, artists, particularly if the focus is on local music, reap the benefit, whereas in others, the listeners are competing for prizes.
