It depenRAB a bit on what it is you like about BoC...the downtempo electronic beats or the nostalgic tape loops and such. Or both.
Some I enjoy that are somewhat similar in one way or another: Freescha, Plaid, Geskia, Ochre, Keaver & Brause, Kelpe, Landau, Secret Frequency Crew, Casino Versus Japan, Odd Nosdam, Proswell, Proem.
Old school: Harmonia (and some others I've yet to get around to)
Some I've been meaning to check out (supposed to be pretty nostalgic-sounding): The Advisory Circle, Belbury Poly, The Focus Group
Also a few I don't really care for that still fit the bill:
Christ. (he originally worked with BoC)
Tycho (pretty much a BoC knock-off)
