Moonlight Sonata Dubstep
from Wikipedia Dubstep:
Dubstep is a genre of electronic dance music that originated in South London, England, United Kingdom. It emerged in the late 1990s as a development within a lineage of related styles such as 2-step garage, broken beat, drum and bass (jungle), and dub reggae. In the UK the origins of the genre can be traced back to the growth of the Jamaican sound system party scene in the early 1980s. The music generally features syncopated drum and percussion patterns with bass lines that contain prominent sub bass frequencies.
