His other solo albums are brilliant. The Adversary is one of my favorite albums, and angL was pretty awesome too.
After is phenomenal, definitely Top 10 material. Would love to see him in America, but he's said he doesn't much like touring, so I wouldn't get my hopes up. Maybe NYC & LA one of these days, but I think it was just before angL came out that he said he didn't plan on doing many shows until later down the road, when he had enough solo material to do a full solo set and then maybe an encore of Emperor songs, instead of just an Emperor set with a few of his own songs (though with three albums out now he might be on his way to getting there). I know so far he's done one show supporting Opeth, and he's doing some festivals this summer.
