We have discovered a French based website that has posted a complete concert of a 2009 Radiohead performance in the Czech Republic. it is obviously with the band's permission, given the use of the In Rainbows marketing design and the notations "audio masters kindly provided by the band" and "strictly not for sale - by the fans for the fans - please share and enjoy."
The full concert is available for download here (be patient; it may take a few moments for the home page to download) and provides the following commentary:
"On 23rd August 2009 a group of Radiohead fans descended on Vystaviste Holesovice Exhibition Hall in Prague on a mission -- to capture the band playing using as many different angles as possible. Bringing together the exceptional talents of many contributors, here is the result."
The full set list is at the site as well.
If you want pulled out videos that have been snipped to YouTube, go to TwentyFourBit and enjoy "15 Steps," "Idioteque" and "There There."
