Alestorm are Scotland's loudest bunch of drunken pirates and have been blasting out pirate metal since 2004. Their shows are like a stranded party with ducks, rum and total chaos. Imagine Jack Sparrow with a keytar and a hangover – that's exactly what it's like. They've hijacked the charts and festivals by turning every audience into a pirate crew. There's no smooth sailing on this cruise, just cannon fire from beer and riffs.
