Twenty-one years after his death, Kurt Cobain’s first official solo single is here. In the process of making his recent documentary Kurt Cobain: Montage Of Heck, director Brett Morgen unearthed a whole bunch of Cobain’s previously unheard home recordings, and those recordings are being released next month as a Kurt Cobain solo album under the name Montage Of Heck: The Home Recordings. But even before that, a 7″ containing Cobain’s cover of the Beatles’ “And I Love Her” and an early demo version of Nirvana rarity “Sappy,” alternately known as “Sad” — both used in the film — is coming out, and today, the latter has arrived. A similar early version of the song has been available on bootlegs and online for a while now, but this is a cleaner, slightly polished up mix, and it sounds both great and heartbreaking. Listen below.

“And I Love Her” b/w/ “Sappy” is out 11/20, and Montage Of Heck: The Home Recordings is out 11/13 via Universal.
