I've got a CD from a dance earlier this year featuring Iration Steppas, King Shiloh and another sound (which escapes me - aargh!). I recorded on my MD at the Brixton Rec. At that particular dance, Mark Iration went to great lengths to tell us about the new website "w w w dot iration steppas dot com - w w w dot iration steppas dot com". Just checked the link and...nice front page, but goes nowhere!
There were loads of sessions for sale on CD on the day, so I'm surprised you haven't come by any. I didn't buy any - but I wish I'd maybe grabbed the odd one.
I also have a recording of Iration Steppas v Zion Train recorded at Dingwalls in 2000. Let me know if you are interested.
