GL&Ws didn't release anything else that I can find. I was bummed to find out Under Pressure quit, but they did leave behind 4 really good 12"s and some EPs, many of which are available still. They slowed things down a bit on later releases, but the quality seemed to get even better on the last couple of outings.
Guns, Liquor, And Whores - "Serpico" 10" (Putrid Filth Conspiracy, 2002, 500(?) pressed, 320 kbps)
