Many think they know the man behind the mic but not matter how many movies, articles or interviews that are out there no one will really know the real Kurt Cobain.

Last night we may have gotten as close as we'll ever get as HBO premiered 'Montage of Heck' a documentary like none before.

Director Brett Morgen uses the Nirvana frontman's owns materials to tell 'his' story... home movies, journal entries, personal recordings and so much more.

If you didn't get the chance to see the documentary you must, in the meantime you can take a read through a great overview done by David Fear and Jason Newman of Rolling Stone called "9 Things We Learned From the Kurt Cobain Doc 'Montage of Heck'".

Take a look below at the preview and make sure you catch the replay on Thursday night, it's also available on HBO on-demand.
