Ceased activity: circa 1986.

A British instrumental quartet, Dif Juz consisted of brothers Dave & Alan Curtis (both guitarists), bassist Gary Bromley and drummer/occasional sax player Richard Thomas. In a recorded interview for Radiobombast (WRFI Community Radio, Ithaca, NY) Richard Thomas explained their name was a random result from use as a place-holder name for booking studio time, but they liked how people interpreted it in various ways. They released two seminal EPs; [r=381650] and [r=381643] in 1981 on the then fledgling 4AD label. The band then departed 4AD for the label Red Flame in 1983 where they released an experimental mini LP [r=381598], following this they toured extensively through 1984 and 1985 supporting Cocteau Twins and [a=Wolfgang Press] before returning to 4AD to record their first full-length LP [r=383702] which featured contributions by Cocteau Twins Elizabeth Fraser (vocals) and Robin Guthrie (production). Shortly thereafter Dif Juz were introduced to Jamaican dub innovator Lee Perry and served as his backing band for a series of shows before eventually attempting to make a record together. The five tracks that were recorded - including a nine-minute version of "The Mighty Quinn" - never quite gelled, despite Robin Guthrie's attempts to mix them and the collaboration remains unreleased.

With the exception of a reissued and re-recorded Huremics and Vibrating Air (respectively) in the form of [r=381633] and a contribution to the 1986 4AD compilation [r=159986] the band effectively disappeared, though the members remained active separately; the Curtis brothers and Ritchie Thomas both recorded parts for This Mortal Coil's [r=184972] album, whilst Thomas would also appear that year on the Cocteau Twins/Harold Budd collaboration [r=77098] playing drums and saxophone. He and Dave Curtis also contributed to The Wolfgang Press' albums [r=260855] and [r=104397], respectively.
It is rumoured that the band's 'final' dissolution came when Richard Thomas became a touring drummer for The Jesus And Mary Chain, though the band never officially split up.

After many years of silence, the posthumous release by 4AD of Huremics and Vibrating Air appeared in the form of [r=237958] in 1999. Coinciding with the album was the creation of a website which appeared to be created by the band. This page ran the banner "By us about us", as well as "More soon" though this never materialized.
