Greg began DJing in 1975 and is regarded as one of the most important figures on the UK dance scene. He enjoyed hugely popular residencies in the early eighties at Wigan Pier and Manchester's majorly influential Legend, having originally started out in his home town of New Brighton. He was a pioneer of mixing in the UK and in 1983 he became the first ‘dance music’ specialist hired for a regular weekly session at Manchester's now legendary Hacienda club. Greg was instrumental in breaking the new electronic, post-disco records coming out of New York, a sound he has dubbed ‘Electro-Funk’.

In 2003 he set up his own website electrofunkroots to document this crucial era in the evolution of dance culture and, having retired from DJ work at the end of 1983, Greg returned to spinning tunes two decades later, receiving plaudits for his red-hot appearances at renowned nights including Electric Chair, Horse Meat Disco, Fabric, Back To Basics, Ministry Of Sound, Asylum, Melting Pot and the Sub Club, to name but a few. Before long he was picking up an ever increasing amount of bookings throughout Europe and, subsequently, worldwide.

In 2005 Tirk Records released ‘Credit to the Edit’, a compilation of re-edits spanning Greg's entire career, some even original tape edits from way back when (Greg still uses his trusty old Revox B77 reel-to-reel tape machine when DJing out). This wasn't his first compilation either, having collaborated on most of the tracks to appear on the Street Sounds ‘UK Electro’ LP in 1984, as well as being the selector behind the ‘Classic Electro Mastercuts’ LP in 1994.

Other firsts for Greg include being the first DJ to mix live on British TV (The Tube in 1983), putting together the first UK radio mixes of their type for Piccadilly 261 in Manchester (beginning 1982) and showing a certain Norman Cook, then a young aspiring DJ called Quentin, how to scratch (Dec ’83). Greg has written for magazines / webzines like Wax Poetics, Clash, Grand Slam and Discopia.

2008 saw Greg go truly global, embarking on an end of year tour that literally took him right around the world, with dates in Japan, Australia and Brazil, following-on from a series of gigs in the US (a return to New York and his San Francisco and LA debuts). Now a firm favourite on the festival circuit in both the UK and Europe, he also played Ibiza for the first time in the summer of 08, including a terrace appearance at the famous We Love Sundays session at Space.

Nominated by DJ magazine for outstanding contribution, and also named amongst their top twenty remixers of all-time, Greg’s edits and mixes continue to feature on the playlists of DJ’s in every continent. During recent times his remix credits have included Grace Jones, The XX, Groove Armada, Bryan Ferry and Simian Mobile Disco, whilst he’s edited tracks by A Guy Called Gerald, Talking Heads, Orchestral Manoeuvres In The Dark, Electronic, Imagination and Missy Elliot, to name a few.

In January 2009 Greg’s reputation was further enhanced when his Essential Mix on BBC Radio 1 became something of an instant classic, receiving almost universal acclaim and, in the process, providing the perfect way to commemorate the 5th anniversary of a remarkable renaissance.

Credit To The Edit Volume 2 was released in November 2009. With tour dates throughout the following months, in the UK, Europe, Japan, Australia and the US, to promote the release.

In April 2010, as part of their Essential Mix 500 special, Radio 1 selected Greg’s Essential Mix as one of 10 classics that spanned the show’s near 17 year history.

Greg’s Blog, ‘Being A DJ’, was launched in June 2010. He describes it as “not a DJ blog as such, but more a blog by someone who happens to be a DJ”. The blog is now well established, with over 200 posts published and half a million people visiting the site to date, with many of Greg’s pieces on various aspects of club culture gaining critical acclaim. He’s also highly active on SoundCloud, where his mixes, edits and podcasts passed the million play mark back in September 2012.

In August 2010 he co-curated (with Jack Hemingway) the Warehouse and Roller Disco areas at the inaugural Vintage Festival at Goodwood, which proved to be an overwhelming success, being named 'Best New Festival' at the UK Festival Awards (Greg also being nominated in the 'Best Feel Good Act Of The Summer' category). The following year he and Jack curated the Warehouse and Style Studio areas as Vintage was hosted at London’s Southbank.

Greg has produced a series of documentative podcasts, Time Capsule, Random Influences and Early 80’s Floorfillers, as well as the long-running blog series, Living To Music, where people are encouraged to listen to a monthly album selection in their home environment. This has served to influence other related events, Colleen Murphy’s successful Classic Album Sundays audiophile experience included.

In 2013 he launched his Schooled In The Classics label.
