You Know You're Right

We can agree that all musicians probably leave behind a veritable trove of unpublished, unpolished recordings. It's in the nature of being a recording artist to try, and eventually scrap, failed attempts at new music. As such, rarely will an artists' work receive a posthumous release, unless said artist is someone whose legacy demands it, or whose legacy includes a crazy bitch-wife trying to make a buck.

The two examples of gigantic posthumous recordings I can best remember were both created as ways to sell larger boxsets or compilations. Those are the Beatles' "Free as a Bird" from the 1995 Anthology release which included the late John Lennon's vocals, and later Nirvana's "You Know Your'e Right" from their 2002 self-titled Best of compilation which included lyrics sung and written by Kurt Cobain.

Of the two, I have to admit I like the Nirvana song much better. But both songs have their own wikipedia pages revealing the story behind how the recordings came to be, and both are worth looking over.
