At first I thought it was "Haa-ken" like the company that makes the Continuum (the cool synth-pad thing that Jordan Rudess first used on Octavarium), but after I became a fan, the band were quick to point out, on Facebook, that their name is pronounced like Bacon, but with a K.
For the longest time I was also mispronouncing Anathema - it's Uh-NATH-eh-ma, not Anna-THE-ma.
And regarding Visions, I'm on the train that loves it too. Something about the conceptual feel of the album where the title track's various themes are woven throughout the whole album, so that when you get to the end, it feels VERY cohesive. That closing epic is just truly amazing, though, especially the last part!
