when i was growing up they started issuing LP albums which played at 33 1/3 rpm, vastly increasing the amount of playing time on one side of a record. before the LP, audio was recorded and distributed on brittle discs made of shellac, running at 78rpm. 78s had a capacity of about 12 minutes; LPs upped that to about 30 minutes which made it possible for classical music fans to listen to an entire movement without changing discs and enabled the development of the rock and roll album.
in 2,000 Jem Finer, a UK-based artist released Longplayer, a 1000-year musical composition that runs continuously and without repetition from its start on January 1, 2000 until its completion on December 31, 2999. Related conceptually to the Long Now project which seeks to build a ten-thousand year clock, Longplayer uses generative forms of music to make a piece that plays for ten to twelve human lifetimes. Longplayer challenges us to take a longer view which takes account of the generations that will come after us.
the longplayer also reminds me of an idea i’ve been intrigued by — the possiblity of (networked) books that never end because authors keep adding layers, tangents and new chapters.
Finer published a book about Longplayer which includes a vinyl disc (LP actually) with samples.
