Really? I found the new Sigh painfully unremarkable.
The guys at angrymetalguy agree with you. I'm starting to wonder if there's a sort of "Sigh fatigue" that's occurring; each new album changes gradually enough that if you listen to one frequently, the next will seem similar yet not as good. I was disappointed with "Scenes from Hell" compared to "Hangman's Hymn" and skipped "In Somniphobia" completely, so it's been a few years since I really gave them a lot of listening. Similar happened with "Gallows Gallery"; I was completely underwhelmed compared to "Imaginary Sonicscape". I've got a full review up now, which can be found here
Latest listen is the new Pitbulls in the Nursery. It's Proggy Tech Death, sort of Gojira or Meshuggah-esque. Which means I should fucking hate it, but 2/3rds through my first listen and I don't, and I can't figure out why. Not as good as their debut though.
