"I Keep My Stuff Inside" is likely my favorite of RR solo works. not only for the nostalgia of being 16 and getting an LP that was padlocked shut and using bolt cutters for the first time (i remember thinking: yes! this is industrial music!) , but all this time later still the compositional intent and sound work holds up as focused and solid. cold, industrial, and a more unusual set of sounds (from the RR i've heard at least) make it stand out. ok, maybe a tiny bit much flanger for me - but hey, that shit wasn't played out yet when this was recorded!
On the flip side of the sound palette, "Male" CS on Truculent Recordings (released about 7 years later) is also a fav despite totally minimal, stream-of-conciousness feel... mostly metal, feedback and voice, this is primitive stuff - but personally i connect with the movements on a cerebral level, making it a tape i'd never get rid of, i play it about once every other year.
Ninth Massacre collection box on Trash Ritual is awesome, total endless filth - i've missed almost all his 90s work except for some downloads but this collection is so awesome i can only hope to keep hearing more and more, somehow.
