A Tribe Called Quest
Cause: There really isn't a particular event we can point to say it lead to A Tribe Called Quest breaking up, it kind of just happened. According to Jarobi, Q-Tip initiated the breakup without the other members knowledge but it didn't come as a suprise to anyone involved. After five albums, three of which are certifiable classics, the group went their separate ways.
Currently: Since their split, the group has reuinited for various performences, notably at multiple Rock The Bells shows and at this year's South by Southwest. The 2011 documentary Beats, Rhymes & Life provided an in-depth look at the group's journey and showcased their problems. But even the film's release was surrounded by controversy and disagreement.
