Really wish these guys were more well known. Same band as Randy Orton's Voices theme and the Blue Mountain State intro. The album is a bit heavy, but most of the songs are between The Killing Kind and Guns, and it's good music to drive to.
The whole movie takes place in a very confined space with only three actors, but does an extremely great job of it. It doesn't use cheap tricks to scare, but it a brewing intensity throughout that continues to build towards the end. The very end is iffy to get into, but the beginning more than enough makes up for it. That's high spoiler territory though, I think it's worth it though.
It mentions on the case, but there's a lot of music in here! Most albums with over 10 songs nowadays have some sort of skit or something to pad the run-time, but this whole thing is just music. It stays cinematic like it's predecessor, but it did drop the space talk interludes from the first. The book with the CD isn't a lyric book, though. It is artistic, but if you were on the fence between physical and download for that reason, might want a download.
