Were he still alive today, Nirvana frontman Kurt Cobain would be 52 years old. Every February 20th, on the day of his birthday, fans wonder what songs he would write if he hadn’t died of suicide nearly 30 years ago. While we’ll never know the answer to that question, an AI is attempting to fill the gap.

A mental health organization called Over the Bridge used Google’s Magenta AI and a generic neural network to examine more than two dozen songs by Nirvana to create a ‘new’ track from the band. “Drowned in the Sun” opens with reverb-soaked plucking before turning into an assault of distorted power chords. “I don’t care/I feel as one, drowned in the sun,” Nirvana tribute band frontman Eric Hogan sings in the chorus. In execution, it sounds not all that dissimilar from “You Know You’re Right,” one of the last songs Nirvana recorded before Cobain’s death in 1994.

Other than the voice of Hogan, everything you hear in the song was generated by the two AI programs Over the Bridge used. The organization first fed Magenta songs as MIDI files so that the software could learn the specific notes and harmonies that made the band’s tunes so iconic. Humorously, Cobain’s loose and aggressive guitar playing style gave Magenta some trouble, with the AI mostly outputting a wall of distortion instead of something akin to his signature melodies. “It was a lot of trial and error,” Over the Bridge board member Sean O’Connor told Rolling Stone. Once they had some musical and lyrical samples, the creative team picked the best bits to record. Most of the instrumentation you hear are MIDI tracks with different effects layered on top.

One thing neither AI gave direction on is how exactly Cobain would have sung the song. Outside of cadence and tone, Hogan had to interpret how the grunge star, who famously suffered from crippling stomach pain, would have channeled his anguish into the lyrics.

Over the Bridge isn’t the first group to use AI to emulate a dead artist. But the intent here is different from similar past projects. “Drowned in the Sun” is part of the organization’s Lost Tapes of the 27 Club initiative. They set out to record AI-generated songs by musicians who died at the age of 27 to raise awareness about mental health resources musicians, and people more generally, can turn to when they feel they need help. The Toronto-based non-profit has a Facebook page where it offers support. It also offers online sessions and workshops.
