Captain Raveman / Ray V. Mann a.k.a Negrobeat is the alias for Marlon Beijer, a breakcore/mashcore/dubcore/dancecore artist from Sweden, which was born in 1988.
In the spring of 2006 Marlon started to make some breakcore/experimental drum 'n' bass tracks in his residence in Sundsvall, Sweden and spread them over soulseek under his alias Negrobeat. The artist name has since been Negrobeat while making tracks.
Sidenote: The artist name was created by a bad translation on google translate and was initially "dark drumbeat", but has become a statement because of misinterpretations.
Negrobeat is also involved in an experimental oriented netlabel called KMPLX.
