Alestorm is probably the biggest surprise in 2008. Just with the first album they got to be known among most of the metalheads and they are currently having an extensive tour and will play in numerous festivals. First known as Battleheart, after that demo in 2006 the company Napalm Records offered them a deal in 2007 and they changed the name due to the similarity with the finnish Battlelore.
Alestorm' style is selfdefined as "true scottish pirate metal", a kind of power-folk metal, that could be a mix of Running Wild and folk epic melodies (and drinking songs environment some times) that could recall to bands like Turisas.
First time I listened to it, it wasn't actually a very good impression. Those cheesy keyboards and melodies and the singer... but after some time I listened more and some songs are quite catchy.
