Franz Ferdinand are posting video diaries on their website as they record their new album in Scotland (here's how the recorded the last one). They're very entertaining little films, showing that not much work is being done. In one, guitarist Nick McCarthy sets off into the countryside with a laptop and an M Box to "record a river and see what it sounds like backwards". In another, Alex Kapranos tries to demonstrate their Ackuset gear, which he says is the key to the Franz sound. But it doesn't work. Ackuset were a Swedish music company who built great-looking tape delays. Franz also have an Acuset mixer, which Alex says is one of only 7 in the world, four of which aren't working. Does anyone know why the Ackuset mixer is so special?
