Hans & Others,
I am also keen on Current 93, and thier first LP 'Nature Unveiled' is one of my all time favourites. I have dozens of releases by them, but not all. The release a LOT of material, sometimes in absurdly limited editions.
I am not aware of any commonality between them and 23 Skiddoo, other than as mentioned before, there shared a similar scene.
Perhaps the only connection I can see is that 23S were on Fetish records, who also released some Throbbing Gristle LPs, who split and Genesis P. Orriidge and Peter Christopherson formed Psychic TV, who included David Tibet, who left to form Current 93. Christopherson formed and still runs Coil (see above)
David Tibet and Stephen Stapleton (Nurse with Wound) seem to be the core of the group, but they have been joined by many others through the years.
Now, will you like them? Hmm, they have had a least two or three phases, from very scary industrial gothic chanting to loopy looping soundscapes to apocalytic folk music, sometimes just with Tibets singing and a guitar.
Think of a crucified Noddy singing to a crew of cats, thats the idea.
The Emblems CD mentioned rightly above is a good starting point to dip your toe, as it covers a wide expanse of thier career.
