I know what you mean. Although, they are extremely complex in every term, but i actually find them very easy to listen to. And it is good because most deathmetal bores the shit out of me because of the lack of variety, akercocke has very little boundaries within themselves i feel. And they come out with some really thunderous riffs like one particular one in a song called 'The Penance'. Once i heard that i just bought the album instantly. Just for that riff. Silly, eh?
