Nevermind, the Nirvana album that helped define a generation, will mark its 20th anniversary in September.

In celebration and to honour its brilliance, Spin has compiled a free tribute album of contemporary artists performing the 13 tracks in original song sequence.

Meat Puppets, Titus Andronicus, the Vaselines, EMA and dear friend Amanda Palmer are a few of the artists included.

Download the album via Spin’s Facebook page and listen now to Amanda’s version of “Polly”. She does have a way with a cover song: thoughtful, respectful, insightful.
