Seiji is a UK producer who has been all over the map stylistically, from Drum & Bass, to Broken Beat to who knows what. He's started sporadically giving away tracks at http://www.seiji.co.uk/
Where you can get this track: http://www.seiji.co.uk/file_download/5/Ravin+A.mp3 which an insanely catchy track that is all over the place. 707 kick? Breakbeats? 303 Line? Detroit-style chunky piano chords? It's cheeky to pitch all those elements into one track, but it's rare that it all hangs together this well.
