Next month, Nirvana fans will be able to get their hands on the 20th anniversary reissues of the group's third and final studio album, In Utero.  Former drummer Dave Grohl says that while he enjoyed making the record, he has mixed feelings about it because it will always remind him of the band's tragic ending.

"You know, it's heartbreaking that we're not a band anymore," Grohl tells British radio station XFM.  "It's heartbreaking that frontman Kurt Cobain's not alive anymore, and it's a beautiful record because it's so real but, for me personally, I don't really like to listen to it too much because it kinda bums me out."

Grohl adds that while he was helping to put together the anniversary packages for In Utero, he marveled at all the memories that came flooding back.  "Looking at the package and seeing all these old pictures and listening to songs that I haven't heard in 20 years and all of these rarities and demos, it's kind of a trip," he reveals.  "I recognize myself back then and I remember what it was like to be in the band but it's hard to believe that that much time has gone by.  It's crazy."

The 20th anniversary editions of In Utero will be available in stores and online at digital retailers on September 24.  The biggest package is the Super Deluxe version, which includes more than 40 previously unreleased demos, rehearsal tracks, B-sides and live performances spread out over three CDs.  The set also includes a DVD that features Nirvana's complete "Live and Loud" concert recorded on December 13, 1993, at Pier 48 in Seattle, as well as 12 additional performances culled from the group's European concerts and TV appearances.
