Thanks to Markus for pointing out to me that there's a 5-track Errors live ep for sale on iTunes, taken from their set supporting Mogwai on 23rd July.
I'd post a direct link to the ep on iTunes, but despite several attempts I can't figure out to get links from iTunes - I'd have thought this would be reasonably obvious but it's eluded me - anyone got any good tips?
Here's hoping for something similar from Mogwai - or even better the full live set as video.
I just typed "Errors ep from iTunes festival" into Google and that preview page was the first link that came up so I just highlighted the address in the address bar and then copied it into the message. Cheers
