Any progressive metal fans in here? If you are, and haven't heard of Periphery, give them a listen NOW. They are an American progressive metal band and they released their self-titled debut album just a few months ago and it sounds amazing. Even if you aren't a progressive metal fan, give them a listen anyway! They sound awesome.

And if you haven't heard of Periphery, chances are you haven't heard of Animals as Leaders either - an instrumental progressive metal solo project by Tosin Abasi. The musical complexity of his songs makes it difficult to believe that all guitar parts are written by just one man!
