Molding itself into a distinctive pirate-themed aesthetic, Alestorm is a speed metal band that formed in Scotland in 2004. With a sound it describes as Patagonian Pirate Polk, or pirate metal, the band couples the slang and swagger of the high-seas with a modern party mentality. Alestorm first captured its rum-soaked anthems on the 2008 album, Captain Morgan's Revenge, earning a quick crossover audience of hard rock fans, heavy metal followers and even the occasional Medieval enthusiast looking for something with a bit more edge.
