Aye! I too have fallen back on a Coil 'trip' lately - partly due to finding a very nice copy of "Gold Is The Metal" at a record fair in my town (not sure the seller even knew what he had!), and partly because of an exhibition held in Dublin before Christmas celebrating the life of John Balance. Well, the last Coil gig was in Dublin, and JB died about three weeks after that, so they timed it to coincide with those 20th anniversaries. At the exhibition there a lot of photos from the gig, JB-related ephemera, paintings by ones that would have moved in Coil-esque circles, like Stephen Stapleton and Drew Mulholland, and a couple of talks on Coil and JB's "life and times". Also, the organisers put together a(nother!) book with a few essays, and - again - photos, ephemera, artwork, lyric sheets, etc. About 50 or 60 A4 pages, hardback; nice little item, but limited to... 93.
As for that Tyr interview - I have it in my head it was the last published one he ever did? Maybe not. Funny, he was quite upbeat and positive in it, but sadly he fell off the wagon as we all know.
Still think the first 'Music To Play In The Dark' is the stand-out of their later work.
