Faster tracks from later albums like ‘Drukqs’ also do well with this treatment — you can find the album slowed-down on YouTube, although I'm not sure that the pitch is changed accordingly, as it changes on vinyl (or rather, that pitch correction was disabled in software).
I also used this method with other tunes, and it works quite well with some stuff like μ-Ziq's idm. However, VLC and sox produce good quality, while ffmpeg doesn't, so gotta watch out for that.
You might dig Radio Soulwax's ‘Cherry Moon on Valium’ mix, which is hardcore and gabber slowed down the same way as techno was back in the day to produce new-beat.
