A lot has changed in the twenty years since my first Bloodstock. What began as a relatively small indoor gathering in the middle of Derby city centre now welcomes around fifteen thousand metal fans from around the world annually. From two days, two halls, a signing room, and a “Metal Market” to four days, four stages, a signing tent, art gallery, gaming zone, and curiosities such as Viking battles and even early morning Heavy Metal Aerobics sessions, the changes to Bloodstock have been gradual but necessary.
