Bloodstock Open Air

Bloodstock Open Air is a yearly heavy metal festival held each August since 2005 at Catton Hall in Derbyshire, England. It is described as the United Kingdom's largest independent metal festival, with more than 100 bands playing on several stages and around 20,000 attendees. It is similar to the nearby Download Festival, but Bloodstock is smaller, focuses on heavy metal, and includes underground bands as well as mainstream ones. Bloodstock also has a New Blood stage, reserved for at least thirty new and unsigned bands; these are chosen through 'Metal to the Masses', regional battle of the bands contests held throughout the UK, Ireland and parts of mainland Europe.

Bloodstock began in 2001 as an indoor event at the Derby Assembly Rooms, gradually growing in size and becoming an outdoor festival in 2005. Its main stages are named after Ronnie James Dio and Sophie Lancaster. Bloodstock also hosts a bust that holds the ashes of Lemmy from Motörhead.
