Alchemy Mastering was founded in 1996 by Barry Grint and Phil Kinrade. It built up a worldwide reputation and earned kudos as one of UK's leading mastering and duplication facilities.
It closed down in 2008, but was relaunched in 2012.

In August 2020 Alchemy Mastering with its facilities had been acquired by Air Mastering with it's main engineers Barry Grint, Phil Kinrade and Kevin Tuffy joining the team at AIR. The operations have been incorporated under the new brand: Alchemy Mastering at AIR, offering a whole range of analogue and digital mastering services.

[NOTE: as for the time being it is not quite clear, if the new brand will be credited as above or if the established name will remain, please stick to Alchemy Mastering as company as for now, unless Alchemy Mastering at AIR is explicitly mentioned.]
