Radiohead release a 'testcast'

Radiohead released a ‘testcast’ last night (November 8) in the build-up to the likely release of their webcast tonight (November 9).

The 20-minute video included footage of the band, minus drummer Phil Selway, performing a cover of Bjork’s track ‘Unravel’, from her 1997 album ‘Homogenic’.

The ‘testcast’, which was streamed on Radiohead.tv at 10pm (GMT) last night, began with Thom Yorke DJing what began as an ambient tune, but then metamorphosed into a bass-led electro track overlaid by icy Radiohead-esque synths.

Then, following twenty seconds of pulsating multi-coloured graphics, the band were shown performing a cover of ‘Unravel’ in a rehearsal studio.

The ‘testcast’ was ended with footage of an unidentified person writing "to whom it may concern" and "I give up" backwards on a blackboard.

As previously reported, the group are thought to be webcasting tonight (November 9) between 9pm and 12am (GMT), after Adam Buxton let some of the plans slip on his BBC 6Music show.
