Sound artist Jonny McHugh has been traversing the festival and recording as he goes. Here's his first instalment - you can download the file in mp3 format or stream it using RealPlayer. Jonny writes:
Expect random things to go around you during the festival. The simple act of getting a coffee at the Pleasance Dome ended in me witnessing a world-record attempt. Dr Bunhead, a festival favourite, has been striving to break the world record for firing the largest number of potatoes from a musket in three minutes. He managed to equal the record but cited problems of poor potato quality - apparently they weren't dry enough, and that meant that they kept on getting stuck in the barrel. Shame.
