Blakkheim I've noticed on the black sessions DVD (wheres the new one!!) that you really get into the solo sessions on Sweet Nurse, its those moments on that DVD when I just wish I could be playing that song.
on the topic of guitar just one thing
What was done with In the White for me was one of the best moments as it went acoustic, I definitly recommend more acoustic (ie A darkness coming) as the albums are very intense, and a soft number can give the mind chance to absorb.. even just one!
