*YouTube’s roll-out of original content continues with a number of new channels to launch in the near future.

“The Warner Sound,” due later this month, promises “exclusive access to superstars, celebrities and breaking talent” along with artist interviews, rare films from the Warner vaults, live events, animated series, scripted comedy and “experimental concepts.” The channel will live-stream performances from Warner Music’s South by Southwest showcase, which will include gigs by T.I., B.o.B., Dr. John, Ed Sheeran, Gary Clark, Jr., Kimbra and Theophilus London.

Other content on the YouTube slate includes “ManTazia” by Cee Lo Green and filmmaker Mikael Colombu,  a short-form series which chronicles “the life, times and music” of the singer and “The Voice” judge.

Actor and director Michael Rapaport will helm a documentary series called “Untitled,” which will also feature WMG artists.

Meanwhile “Staged” takes the lyrics of popular songs and “re-imagines them as the script of a drama.” The first episode will feature the words of Gym Class Heroes.

“The Live Room” will feature intimate performances shot in recording studios all over the world. Promised for the premiere: B.o.B. at Tree Sound Studios in Atlanta. Regina Spektor is slated for a future episode.

“Countdown To”… takes a look at the final days before a hotly-anticipated album comes out, and in Finding Cody Simpson, fans will be able to create their own adventure series based around the teen star.

In October 2011, YouTube announced nearly 100 new channels, including ones by the music-focused Vice, Bowery Presents, Pitchfork and Fuse. BonnarooTV is scheduled to launch on March 13.
