Open Reel Ensemble Cyklepedia Wikipedia Magnetic Tape Music
Japanese musicians commemorated Wikipedia’s 25th anniversary with a unique composition made up entirely of Wikipedia entries. Open Reel Ensemble produced the song as part of a virtual birthday celebration, and it’s a true journey because it’s totally made up of ancient reel-to-reel equipment that also function as instruments. Every sound is produced by physically moving the tape over the heads, with no artificial samples added after the fact.

Back in 1984, Akai released the PJ-11, a compact stereo system that brought some fresh ideas to portable audio.

Sony engineers decided to change that. They created a portable turntable that plays records standing upright, runs on four AA batteries, and weighs so little that it can be carried anywhere.
