VIDEO : MTV Premiering First Snapchat Music Doc at SXSW

MTV is teaming up with A$AP Ferg at South by Southwest to launch its first Snapchat music documentary, Mashable has learned exclusively. The documentary ? which will be available on MTV's Snapchat story, not its Discover channel ? will roll out live as filmed on Wednesday in 10-second increments. "We always do a lot of behind-the-scenes stuff on our channel, and this year we wanted to turn that into a real story. "We don?t want them to get bored, we don?t want them to say ?oh MTV?s doing X Y and Z again and and again.'
