Judging by this latest album, (which, I've been told, is less punk and more rock than their previous outings) The Gaslight Anthem are a great rock band who seem to have found the middle between Counting Crows' slightly rougher songs and some of Foo Fighters' softer song. "Bring It On", the third track, is a great rock song, whereas the song that follows it, "The Diamond Street Church Choir", leans closer to the aforementioned Counting Crows influence.
However, the quality is there pretty much across the board. The titular "American Slang" just sounds like a band having some great fun, with a catchy tune and lyrics that stuck in my mind. "Boxer" is my least liked out of all the tunes, and even that I most definitely considered worthy of listening to all the way through. "The Queen of Lower Chelsea" is simply fantastic, almost feeling like a song Arctic Monkeys might have written if all of their albums had sounded similar to (and maintained the quality of) All That You Say I Am, That's What I'm Not. It goes without saying that the Arctic Monkeys are awesome, and so is this song. This album receives a whole-hearted recommendation from me. Get it, it's worth it so much. 5/5
