Lee Purkis aka In Sync was one of the first people to actively support, promote and play house and techno in the UK. He made trips to Chicago and Detroit in the late 1980s to find the records that were otherwise unavailable to British DJs. In the early 1990s, Purkis was instrumental in setting up FatCat records in Crawley, Sussex, before it moved to London. Long since closed down, Purkis' brainchild still remains one of the UK's most revered record stores, although few people are aware of his integral part in its conception.

Purkis' recording medium of choice was a standard analogue compact cassette, normally recorded to using a 4 track cassette recorder.

Purkis was partly responsible for the 10th Planet label, along with collaborative partners Chris Hartley & David Manuel, with whom he released under the Insync vs. Mysteron mantle.

Aside from those releases correctly credited to known aliases, Purkis and his 10th Planet associates were also involved in music that made it onto releases on Fragmented Records (FMD LP 001 & FMD CD 001), Relief Records (RR760), Basement 282 (PT17), Target Records (US) (TR-001) and Peacefrog Records (PFG 058, PFG 059/PFG 059 CD), although they were never given any printed credits for these works.

After a long period away from the scene, January 2006 saw Purkis kick off a new label, Fortune8.
