Martian's news page lists Seth Lakeman as recording there in 2007. That's the last and only recording artist mentioned, apart from Tori and even her info isn't up to date anymore on there. That would indicate to me it's not doing so well, business-wise. It could be the location, so far off the beaten track (Cornwall is a pig to get to in UK terms), or it could be overpriced or something, but it doesn't look like they get much in the way of high-profile business. I wonder how much debt they ploughed themselves into to build all the extra facilities? It's certainly quite a flash set-up there.
