Krist Novoselic along side Dave Grohl talked about the reissue of 'Nevermind' which celebrates it's 30th anniversary in September. The two hinted at some rare material that might appear on the reissue. Something that Nirvana fans have been hoping and searching for. Krist was determined not to ruin the surprise for us. That's ok Krist, grunge was a big enough surprise for all of us! I'm looking forward to September. https://www.nme.com/news/music/nirvanas-krist-novoselic-teases-nevermind-30th-anniversary-reissue-2971174
