Researcher's AI turns Sigur R贸s single into 24-hour TV soundtrack
Primary page content
The band Sigur Rós has produced a 24-hour televised journey around the entire Icelandic coast, set to an evolving version of a single song generated using artificial intelligence developed at Goldsmiths.
Update: On Tuesday 29 June Sigur R贸s released Route One in its entirety on YouTube 360, accompanied by a free ios audio app utilising Bronze. Visit to download.
In 2011 Dr Mick Grierson from the Department of Computing created the commercial music format, , which manipulates and transforms every aspect of a track to create a unique version on each listen, while the song remains recognisable to the listener.
Music is no longer static, but producers and composers can create subtly different mixes with each play, while still retaining the quality and balance of the original mix.
From 20-21 June, the experimental Icelandic post-rock act unveiled their film Route One live on Iceland鈥檚 National Television 鈥 and streamed globally via YouTube 鈥 with a constantly evolving soundtrack based around elements of their new song 脫ve冒ur.
The individual musical elements of the unreleased song, and current Sigur R贸s festival set opener, were seeded through evolving music program Bronze to create a unique ephemeral sonic experience.
Dr Grierson says: 鈥淏ronze has been used to make several releases on iPhone, iPad and desktop over the last few years. Each time you listen to a song it sounds different, but unlike similar generative music approaches that produce random mixes, artists can control exactly how different the next version of the track will be in quite complex ways.
鈥淚t's a form of Artificial Intelligence that takes examples from the producers and uses these to create the music based on a probability matrix.鈥

Starting on the Summer Solstice and continuing throughout the longest day of the year, Route One is a 1332km journey the whole way round Iceland鈥檚 coastal ring road 鈥 a project described as 鈥淪low TV鈥.
Commenting on the idea, Sigur R贸s鈥檚 J贸nsi Birgisson said: 鈥淚n a day and age of instant gratification and everything moving so fast, we wanted to do the exact opposite. Slow TV is counteractive to the world we live in, in that it happens in real time and real slow.鈥
Driving anti-clockwise round the island, the journey passed many of the country鈥檚 most notable landmarks, including Vatnaj枚kull, Europe鈥檚 largest ice-sheet; the glacial lagoon, J枚kuls谩rl贸n; as well as the East Fjords and the desolate black sands of M枚冒rudalur.
Bronze was launched in 2012 in partnership with musician Gwilym Gold, who became the first artist to use it on a music release. Working with research assistant Chris Kiefer and PhD students Parag Mital and Dan Jones, Dr Mick Grierson led the Goldsmiths team as part of the Sound, Image and Brain project funded by the AHRC.
