Nirvana‘s 1993 album In Utero will be re-released to mark its 20th anniversary on September 23.

A remastered version of the band’s third and final studio album will feature 70 tracks including previously unreleased recordings and demos, B-sides and compilation tracks and live material featuring the band’s final touring line-up of Kurt Cobain, Krist Novoselic and Dave Grohl and Pat Smear. It will also include the Live And Loud show from Seattle’s Pier 48 on December 13, 1993. A separate DVD release of that show will also be released on September 23.

Earlier this week, members of staff at US record label Sub Pop posed as Nirvana after a misguided fan of the band wrote to the label requesting that Kurt Cobain and co record a video message for a university football team in Virginia – watch it below.

An unnamed fan, who claimed to be the mascot for Virginia Tech, wrote to Sub Pop requesting that Nirvana “send a quick video” and say: “What up Virginia Tech? This is Nirvana! Just wanted to wish you a Happy Homecoming week and good luck at the game this Saturday. Let’s Go Hokies!” Not wanting to disappoint the letter writer, four members of the Sub Pop staff filmed a video of themselves giving the message and texted it to her. A screengrab of her reply to the label shows that she said: “You are the best, thank you guys, you are awesome,” upon receiving the video.
