Sure, there's plenty of Solefald and Borknagar trivia to impress him with. For example, did you know that Quintessence was actually recorded in a cave that's in a mountainside? Now, you'd think that it would make it sound awful, being in such a reflective environment and out in the elements, but the mix of music and location was just so damned epic that it gave the recording the clarity to make it sound the way it does. In fact, had it been recorded in a studio, the building would have exploded.
The problem is, nobody would have believed that, given recording technology of the time, so they had to say it was recorded in a studio.
