After four studio albums together, the original BAD line-up broke up in 1989. Williams, together with Don Letts and drummer Greg Roberts, formed the band Screaming Target after Big Audio Dynamite's demise.[1] Later, Williams joined Dreadzone, a group with his former bandmate Dan Donovan, and, again, Greg Roberts.
In March 2007, it was announced that—in addition to his work with Dreadzone, Williams would be a touring bassist for Carbon/Silicon, Mick Jones' latest musical endeavor. Williams appeared in the band's music video for "The News,"[2] and is featured as a band member on the official Carbon/Silicon website.[3]
Williams rejoined the re-formed Big Audio Dynamite in 2011, which broke up again that same year.
Williams also featured in the science fiction action film The Fifth Element (1997) as the fuel loader of the Fhloston Paradise shuttle.
