Gavin Griffin, also known as GMJ, has been a prominent figure in underground electronic dance music for over two decades. Forging a successful career as a DJ, event organizer and producer, Gavin is a pioneering force in the Melbourne scene and has performed all over the globe. Playing alongside some of the world’s leading names in progressive, it was a natural evolution that Gavin would bring his passion for hypnotic soundscapes and deep grooves to the studio setting. In 2007 the GMJ project was born and has since landed on iconic imprints including Replug, Sudbeat, AnjunaDeep, Proton, Parquet, Balance Music, Hoomidaas and many more. Spacious yet powerful, the GMJ sound has been supported by luminaries such as Hernan Cattaneo, Cid Inc, Guy J, Nick Warren, Alex O’Rion, and regularly features on the front pages & charts of the world’s biggest dance music retailer Beatport.com, with numerous top 10 entries and a rise in 2021 & 2022 to the top 10 selling artists on beatstats in the genre. Touring has followed extensively through his native Australia and beyond to locations such as Sri Lanka, Europe, Japan, India, New Zealand, Noumea and many more. Alongside great friend and collaborator Matter, the pair formed their “Meanwhile Recordings” imprint in 2020, which has gone on to become one of the most acclaimed and respected labels in progressive house, housing the pairs own productions and becoming a destination imprint for the world's best.
