If you like TDH, go for "The Light at the end of the world", it is the one previous to TDH, and is pretty similar. After that, "The Angel & the Dark River is probably the next one to get (no death vocals on this), then "Like Gods of the Sun" (assuming you want to keep buying their albums
![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
). After that, if you want some all-death vocal stuff, give "As the flower withers" or "Trinity" a shot, or for a more 'modern' approach (again, all-clean vocals), "34.788% complete".
In regards to 34.788%, I hated it initially, but now really like it. It is a little different from their other stuff, like I mentioned before, more of a 'modern' feel to it. It kinda lacks the over-the-top dramatics of other albums, the songs are more direct and to the point. And there is a trip-hop song, which most people hate, and everyone that hates the album seems to have based their opinion solely on that song, rather than all the others (it's a rather boring song too, but there are 6 others to get into). The opening track, "The Whore, the Cook, and the Mother" is one of their best, and quite stunning.
