Crystal Rings (2008/2009) is a "remix" of two chamber works by Austrian-Icelandic composer Páll Pampichler Pálsson (b. 1928). Every sound originally belonged to a recording of one of these pieces. Then things happened to them, leaving no recognizable parts from the originals.
The original version was a commission from Icelandic State Radio, celebrating Pálsson's 80th anniversary. The work was originally produced in stereo, but later remixed to surround and slightly reworked.
