The shoulder-length blond hair. The stubble. The youthful face with its permanently weary gaze.
Kurt Cobain is still instantly recognisable as one of the most iconic faces of the 1990s, and the most important musician of the grunge scene, reports BBC.
It is almost staggering to realise he would now be entering his sixth decade.
On the day the Nirvana singer would have turned 50, what explains his enduring influence?
His daughter Frances Bean Cobain, who was not even two years old when Kurt took his life in 1994 at the age of 27, tweeted a happy birthday message to her father.
Fans have also been tweeting their favourite quotes, with this one a particular favourite:
‘If any of you in any way hate homosexuals, people of a different colour or women please do this one favour for us - don’t come to our shows and don’t buy our records.’
Kurt was outspoken on gay rights, homophobia and sexism. He said he wished he’d been gay, just to annoy homophobes, and often wore dresses to protest against sexism.
‘Wearing a dress shows I can be as feminine as I want,’ he told the LA Times, in a jab at the macho undercurrents he detested in rock. ‘I’m a heterosexual... big deal. But if I was a homosexual, it wouldn’t matter either.’
He admitted to spray-painting cars with ‘God is gay’ and was once arrested for graffitiing by police in Aberdeen, Washington State.
The band came to represent Generation X but he had no time for apathy.
‘I’m disgusted by my own and my generation’s apathy. I’m disgusted at what we allow to go on, by how spineless, lethargic and guilty we are of not standing up against racism, sexism and all those other ‘isms’ that the counterculture has been whining about for years while they sit and enforce those same attitudes every night on their televisions and in the magazines.’
‘What’s alternative? What’s counterculture? What’s cool? Who knows? Who cares? If chasing cool is important to you, you’re an idiot!’, Kurt said in a 1991 interview.
And, for someone who came to be seen as a spokesperson for his generation, Kurt rejected any hype about their so-called ‘overnight’ success (actually five years in the making).
‘I’m not into ambition or salesmanship, we’re not some new trend. We never meant or tried to be cool, or be a ‘buzz’ band. It never even entered our minds.’
It would be easier to list who Nirvana didn’t influence than who they did. Lana Del Rey, Blink-182, Justin Timberlake and Jay Z have all quoted Nirvana songs in their own lyrics, while Weezer once played an entire concert of Nirvana covers.
‘Cobain changed the course of where the music went,’ said Vernon Reid of rock band Living Colour. ‘There are certain people where you can see the axis of musical history twisting on them: Hendrix was pivotal, Prince was pivotal, Cobain was pivotal.’
Nirvana launched a million garage bands - the simple barre chords that open Smells Like Teen Spirit are the first song many guitarists learn - and helped foster a do-it-yourself attitude that now permeates everything from indie to pop and grime.
They introduced legions of fans to alternative music, pushing associated acts like Soundgarden, Pearl Jam and Kurt’s favourites The Pixies into the mainstream.
But speaking in 1991, Kurt downplayed his own musical talents.
‘I don’t understand anything technical about music at all. I don’t understand any of it, why you can’t put these sounds together with those sounds. I only know what sounds good to us.
‘I, or we as a band, never really copied anybody or spent time learning other people’s songs. We were never good enough or had the patience to do it! So we put that energy into putting our own stuff together. We’re from the learn-as-you-play school. We’re still in it.’
Anyone lucky enough to have seen Nirvana play live would attest to the power of their live performances.
But some became remembered for other reasons.
When they played at Top of the Pops in 1991, the band were advised to sing live over a pre-recorded backing track. Nirvana decided they’d rather not, thanks all the same.
Instead, Kurt sang Smells Like Teen Spirit in a much lower voice, changed some of the lyrics and barely touched his guitar. The rest of the band performed in a similar vein, emphasising the fact they were very much not playing it live.
At Reading Festival Kurt came on stage on a wheel chair before singing one line and then pretending to collapse on stage.
Similarly striking was their appearance at the 1992 Reading Festival.
It was August bank holiday weekend and rumours had been circulating that Kurt and his wife Courtney Love, who’d just given birth to Frances Bean, were deeply unwell. In response, he came on stage in a wheelchair, wearing a hospital gown and a blond wig, sticking two fingers up at the music press.
It was Nirvana’s first time headlining the festival - but it would also be their last UK performance.
Dave Grohl said they had barely rehearsed but, somehow, that didn’t matter.
Given the cult that has grown around Nirvana’s music and Kurt’s death, it’s easy to forget the star was unusually eloquent and passionate.
