Monsters of Rock was an annual (hard rock / heavy metal) music festival held in Castle Donington, England, that branched into other locations such as the Netherlands, Spain, Italy, Germany, France, Sweden, Argentina, Brazil, the United States and the former Soviet Union.
In 1979, promoter Paul Loasby, along with Maurice Jones, planned a one-day festival dedicated specifically for bands within the hard rock and heavy metal genre. Loasby was an established and successful promoter working that year on the Rainbow UK tour and penned the festival as the final show of the tour for the band to headline. Jones knew the owner of the Donington Park race track, Tom Wheatcroft, located next to the village of Castle Donington in Leicestershire, England, and the site was chosen to host the event.
Donington Park was unknown as a major location but its location in the East Midlands next to the M1, A42 and A50 allowed for better transportation to the site from around the country. Additionally the site ground level sloped which allowed for a better viewing for the audience throughout the site.
The first Monsters of Rock line-up consisted of a mix of British and international bands and was a success with 35,000 heavy metal fans attending. Although only conceived as a one off event, it was mentioned on the day the idea that the festival will return the following year and the first edition birthed what would become a regular festival for the next 15 years, becoming synonymous as a Mecca for fans of the genre and further establishing the Midlands as the home of heavy metal.
