Gordon began his career as a DJ called GT Sampler back in 1988 just in time for the Dance Music Explosion in Scotland in the early 90's. He held a residency at Melville's in Livingston.

Gordon & [[artist:Technotrance]] formed Suburban Delay in 1991 and wrote their first track 'Energy Rush'. Gordon later performed all over the UK with Suburban Delay and later went on to perform as D-Tox which had a much harder edge.

His sister is [[artist:Gillian Tennant]].
