A new exhibition titled "Kurt Cobain Unplugged" will open in London, UK in June, celebrating the enduring influence of Kurt Cobain and NIRVANA. The exhibition will feature Cobain's rare Martin D-18E guitar, used in the iconic 1993 "MTV Unplugged" performance, along with his olive-green mohair cardigan. Co-curated by a rock journalist and a museum curator, the exhibition will offer fans a chance to explore Cobain's world and the legacy of NIRVANA. The guitar, which became the most expensive ever sold at auction in 2020, played a significant role in shaping NIRVANA's music and is a key highlight of the exhibition.
