Icelandic composer Johann Johannson's IBM 1401: A User's Manual is a modern classical OK Computer. Using 30-year-old tapes from the first commercially available computer in his country, Johannsson's work is a string and sample elegy for outmoded technology, future nostalgia and that pie-eyed mid-century idea of progress. At times recalling Aaron Copland's Appalachian Spring, at times homeland pals Sigur Ros, Johannsson's IBM 1401 smiles on yesterday's landscapes full of humming, bleeping boxes.
