Take a look at this solid preview of one of our favorite music documentaries, which features many of the disco music legends we have come to love. Featuring music and interviews from the likes of Anita Ward, Nile Rodgers, and many more. We have been waiting for this episode since the announcement of this year’s lineup. If this preview is any indication, this episode is going to be touching on some very compelling issues. If you miss it tonight on TVOne (Check local listings), check back here tomorrow.
