I forgot where I first heard about them, but I started listening to some of their songs a few weeks ago and really got into them; I couldn't get bored with them and had some of their catchy tunes staying with me throughout the day. Needless to say, I decided I'd buy it the other day (I think it was two days ago). I've been extremely pleased with it!
Their songs flow smoothly and they are all catchy. The singing and screaming is well done. Their sound reminds me of a pleasant mix of hardcore and rock--but not how some bands try to mix metal and pop and in the end it sounds crappy and like they can't decide what they want to do. The Amity Affliction have their own sound in that regard, and it works great, with hardcore guitars and drums and screaming mixed seamlessly with singing and guitar work that complements it.
This has become one of my favorite albums and I would recommend it to anyone who likes hardcore rock or metal. You won't be disappointed!
