Radiohead’s Tour may well be using the first exclusively LED tour-lighting system.
From Radiohead’s official website:
Andi Watson, the lighting and visuals designer for Radiohead since their club days, has a reputation for innovation and attention to detail. It was his creative genius and strong support of the concept that brought him to suggest going further and use LED. Back to a direct power demand system but using much less power at 100%.
