It’s not very current but I think it’s worth mentioning Symphony for Dot Matrix Printers by [The User]. It’s “a work which transforms obsolete office technology into an instrument for musical performance. The Symphony focuses the listener’s attention on a nearly forgotten technology: the dot-matrix printer. Specifically, it employs the noises the printers make as the sole sound source for a musical composition. Leaving the constituent elements untouched, the process imposes a new order upon them, reorganising the sounds along a musical structure.” Make sure you check out the media page and there are some additional sound samples from the CD, Symphony #2 For Dot Matrix Printers, here. It’s actually very cool. [via]
