I had a listen to Promise and Terror for the first time in quite awhile tonight. I must say that this song (as well as Ghost in the Machine and Stare at the Sun from Silicon Messiah) is Blaze at his best. This song is about his wife Debbie, who passed away in 2008.
The Bermudez brothers and Walsh were great.
Obviously his life is alot better now, he has since remarried and have a daughter, and I think he is not as depressed now, so I think he has no reason to write very personal stuff, and therefore decided to go with "space metal" with the new album.
