A gig by The Charlatans has been sent to Japan in a first-of-its-kind broadcast of Super Hi-Vision TV.
The technology, 16 times sharper than HDTV, has been developed by Japanese public broadcaster NHK.
The standard could be used on giant public viewing screens, some of which may be in place for the 2012 Olympics.
NHK hope to broadcast in Super Hi-Vision by 2020, although no television currently exists that can fully show off the 7680-by-4320 pixel signal.
The "full HD" currently available means a display of 1920 by 1080 pixels - a quarter the number of pixels both vertically and a quarter horizontally.
Dr Keiichi Kubota, head of research and development at NHK, described the transmission as a "historic moment".
A trial run of the technology was shown off at a conference in 2008, beaming a live image from City Hall in London to a conference centre in Amsterdam.
NHK has since been working to make the cameras significantly smaller and in partnership with the BBC's Research and Development division has developed methods of compressing the video signals.
At full resolution, those signals are transmitted at a staggering 24Gb/s, and the Super Hi-Vision camera was made possible by NHK's development of an optical data transmitter inside that can handle the stream.
In Wednesday's demonstration, a camera - one of just three of its kind in the world - captured a live set by the group The Charlatans.
In an adjacent room, spectators watched the performance on a 103-inch plasma television, also developed by NHK.
A prototype that represents the leading edge of television technology, it is still just one-fourth the resolution that the Super Hi-Vision signal contains.
An audience in Tokyo watched the gig on a significantly larger screen, thanks in part to Janet, the UK's 40Gbit/s education and research network that was used to stream the broadcast.
for fans in the UK eager to hear the set, it will be rebroadcast on Thursday 30 September and can be viewed on the 6Music website.
