OK, a few thoughts:
1) FUCK
2) Saddly I must say I'm not totally surprised by this, Anathema have been on the path of commercialism for a few years now and, while there is nothing at all wrong with that, I do see this as a condition of the mainstream, where everything is expendable to advance the band. First Duncan, now Danny, hell those are the two song writers (forget Vinny who what, wrote one (albeit great) song on A4, and John who, well, how effective is a drummer as a songwriter anyway (I mean in terms of chord and melody writing)).
3) Didn't Duncan leave because him and Danny were always fighting? Now they are in the same band? Did I miss something?
4) Why don't Antimatter change their name to Anathema and tell the others to fuck off?
5) Are you really satisfied with the explanation that Danny has given? I say this, because I miss the old days of metal, where if shit happened, the band told you about it, none of this crap that seems to be acceptable these days where people leave and say "oh, nothing important, creative differences, y'know..". I have all their albums, the video, I've sunk a few hundred dollars into the band, not to mention the MASSIVE emotional impact every one of their albums (except the last) has had on me (and when I discovered them, it was a life changing experiance, and I don't say this lightly (in combination with MDB)). The "Oh, I'm much happier doing this" doesn't sit well with me. Oh well, atleast it's better than the explanation Dave gave. (and in saying all this, no I dont' think the band 'owe' me anything, I realise it's probably extremely personal, what with the brothers and stuff, but I hope you get my point)
6) Fuck, once again
7) HOORAY. The return of the Anathema I know and love!! (well, Antimatter anyway...)
