Jem Finer first collaborated with Artangel on Longplayer, a one-thousand-year-long musical composition that began playing at midnight on 31 December 1999. This collaboration has continued throughout the years marked by events including Longplayer Live 2009, the ongoing Longplayer Conversations series, and, most recently, with the Longplayer Assembly.
Known as an artist and musician, Finer is also an award-winning composer. His works include 'Score for Hole in the Ground' in which underground falling water plays on hidden percussive instruments. Meanwhile 'The Centre of the Universe' is a radio observatory of sorts, reimagined as a drawing machine and supercomputer, likened to a composing machine where the flow of ball bearings, carrying information through labyrinthine circuits of mechanical computational units, were used to calculate minimal melodic phrases.
