Mindless Behavior is a boy band from Los Angeles that was assembled in 2008. Before even releasing a recording, the quartet trained on rudimentary singing and dancing skills, to make sure when Mindless Behavior did go on tour and showcase itself to the public, it would be a well oiled machine. The group has opened up for Justin Beiber and Backstreet Boys on tour; and even though the group is relatively young (with all the members being in their teens), it has found a fairly large fan base that thinks highly of the band's characteristically adolescent vocal style.
