'London’s Royal Opera House is currently home to a production of Last Days, a work from composer Oliver Leith which adapts Gus Van Sant’s film of the same name — which itself was inspired by the final days of Cobain’s life.'
'Polachek does not appear on stage herself, but sang a pre-recorded Leith composition during a scene where the opera’s central character, according to Clements, “plays an unmistakably Nirvana-like riff on his guitar in the opera’s only explicit Cobain reference.”' - via https://www.insidehook.com/daily_brief/music/kurt-cobain-inspired-opera-just-opened-london-last-days
