Smashing Pumpkins frontman Billy Corgan has tried to correct the public misconception that Nirvana icon Kurt Cobain was a slacker.

Speaking to Metallica’s Lars Ulrich on his It’s Electric radio show on Beats 1, Corgan recalled how his band “Would get castigated for working too hard” in the ’90s, claiming Courtney Love told him that Smashing Pumpkins’ first album was “Unfair because it sounds like a second album”.

Corgan went on to bust the myth that Cobain “Would roll out of bed, take some drugs and write a fucking classic”.

“Kurt Cobain as a lyricist, as a songwriter, as visionary was a fucking assassin. He was great at what he did and it’s a shame he didn’t do more of it,” Corgan argued.

“And listening to Nirvana’s early demos, listening to Nirvana’s first album, listening to the second album – his voice is changing. It’s not just changing physically, he’s finding the character of Kurt Cobain.”

Elsewhere in the interview, Corgan said that a Smashing Pumpkins reunion with D’Arcy Wretzky would be a “Shitty reality show”.

Describing their phone calls as “Very pleasant”, Corgan said that “Only when it became obvious that it wasn’t the way she wanted it to be, it turned into this thing that turned very reminiscent of the past”.
