I don't like much deathcore, but I do like this album. It definitely displays a musical ability that most deathcore bands lack, not just chug chug chug grunt chug. I find this more energetic than Planetary Duality. However, I do really like the direction they went with Autotheism (albeit that album was a total grower for me).
Track 6 IS called "Leira". "Leira" makes more sense then "Leica", which is a camera brand.
"until that drummer fucks up and can't keep the beat. " Can you name the exact time he "fucks up"? I'd like to hear that, since I'm pretty sure the drumming is all spot on.
