“While you can probably declare history on something that doesn't make a sound, it is a little more difficult to declare radio on inaudible objects. Assuming we've all heard silence before; assuming there is a beginning of radio; assuming a history of radio is both audible and understandable – then there must be a birthday party! But how do you package a present for radio? How do you open them, what's inside? To solve this dilemma, John Hopkins and August Black built a loop in the network to measure, explore and examine the parts of a birthday that make up a whole. But, since you can't have a cake and eat it too, it is most unlikely that the two artists will answer any of the dire questions.”
August Black und John Hopkins
Beside a live feed coming in from the network, the artists prepared and used some of their own material for “Birthday Loop”. John Hopkins played a lot of his own recordings, including "Happy Birthday" in Icelandic, while August Black mixed the loop and played raw image files as audio.
