Toronto organization Over the Bridge has created “new” Nirvana, Amy Winehouse, Jimi Hendrix, Doors songs using artificial-intelligence software to approximate their songwriting, Rolling Stone reports. In "new" Nirvana case, everything other than the vocals - the work of Nirvana tribute band frontman Eric Hogan - from the turns of phrase to the reckless guitar performance, is the work of computers. The tune, titled 'Drowned in the Sun', is part of Lost Tapes of the 27 Club, a project featuring songs written and mostly performed by machines in the styles of other musicians who died at 27: Cobain, Jimi Hendrix ('You're Gonna Kill Me'), Jim Morrison ('The Roads Are Alive'), and Amy Winehouse ('Man I Know'). Each track is the result of AI programs analyzing up to 30 songs by each artist and granularly studying the tracks’ vocal melodies, chord changes, guitar riffs and solos, drum patterns, and lyrics to guess what their “new” compositions would sound like. Over the Bridge helps members of the music industry struggling with mental illness.
