Mario Dederichs (born July 11, 1988) is a German composer, singer and guitarist. He was born to an entirely non-musical family. His family didn't possess any musical instruments until he bought a very cheap keyboard at the age of ten. He enjoyed playing songs he knew on his keyboard and also got into composing original songs.
Turnerzero is a fledgling composer of video game inspired, chiptune-esque soundtrack pieces. Getting his start in MIDI composition at a young age, Turnerzero or just "Turner" seeks to keep the classic sounds of the 16-bit generation standing strong as well as invigorate his listeners with hard-hitting battle music.
Some of the current last.fm tracks are lo-fi renderings which don't have the original SID left. To find my surviving SIDs in the High Voltage SID Collection, search for "Teemu Mäki" at http://www.c64.org/sidfind/index.php . The publicly released SIDs are also available as MP3s recorded on real SID hardware as part of the SOASC= project.
