Yeah, Delerium has slowly evolved into electro-dance-pop over the decades (and Karma in 1997 was the second-last album I really liked), but their earlier albums were more the industrial stuff you might expect from FLA / Noise Unit / etc -- they have staggering array of projects under different names.
Around the same time I found out about "Koran" above, I discovered two new Delerium tracks I'd never heard of before, because they were only released on a compilation album, Cryogenic Studio Vol. 2, which was never classified under the name Delerium anywhere (usually FLA or Synaesthesia, iirc).
