Well these guy's myspace says Pop Punk/Hardcore, and that's pretty much exactly it. Just imagine your average Pop Punk/Melodic Hardcore band, and add a healthy balance of double-kicks, chuggy breakdowns, interesting guitar-work, throaty growls and a hardcore attitude to burn and you generally have ADTR, who are anything but average.
The drumming is above average, the guitars melodies are amazing, and the vocals are immaculate.
This album is only $1.50 more than the un-enhanced one, and you get a lot for that $1.50, including some of the best songs on the album and an awesomne dvd. The 10-song live show is them playing on a tiny stage in a cramped hall with a nuts audience; epic. I had the amazing opportunity to see these guys play down here in NZ, and they do put on one heck of a live show.
I would have to say that for me personally, this has been the greatest release of 2008. I can't really recommend this to fans of a certain band because there isn't really anyone else like ADTR. If you've never heard these guys I would definitely recommend checking them out though.
