Martin Backes is a Berlin-based audiovisual artist. In his latest work What Do Machines Sing Of?, he asks the old question of how a computer can communicate, or rather evoke, human sentiment. An automated machine that sings 90s ballads in a digital way, but not in a way which feels distant and cold. And that is what Backes has done very skillfully: retaining the sentimental aspect of vocal intonations, while stripping the songs bare.
