After Jake Rivera previously started Stiff Records, Radar Records and F-Beat Records, he founded Demon Records with Andrew Lauder and Elvis Costello in 1980.

In 1998 Demon was acquired by Crimson Productions and the record label was merged with its Westside Records operation.

The company is now known as the Demon Music Group and releases records by artists such as Jane McDonald and Marti Pellow, as well as a number of compilation brands such as the "Harmless" funk and the "Nascente" world music collections. As well as these Demon is also the European licensee of the Hi Records catalog.

Demon Music Group (DMG) is currently the UK’s largest independent record company, specialising in the creative production and marketing of CDs and music DVDs. There are 17 labels spanning all genres, formats and price points. From low-price single CDs, through to mid-price box sets and full-price TV advertised albums. The repertoire is sourced from both major and independent companies around the world as well as their own vast library of rights that includes artists such as Marc Bolan & T.Rex, Al Green and Ian Dury & The Blockheads.
