Nearly 15 years have passed since the original broadcast of MTV's unplugged set, and now it is finally available on video for the first time.  The DVD features the entire, unedited performance and the edited broadcast version--all in Dolby stereo and 5.1 Surround Sound.   The cd version was released in 1994 (soon after Cobain's death), and went on to become Nirvana's second best selling cd of all time.  As an extra bonus to the DVD, a 14-minute interview segment called Bare Witness produced by MTV focuses on those involved in the producing and taping of the set.  Taped just months before Cobain's death, Unplugged in NY is both startingly raw and disturbingly planned, with the band playing amongst candles and stargazer lillies--more than a few people noted it seemed like a funeral.
