    The bassline from Bacteria is a twisted up sample from 1992 track Disintegrator - Disintegrated on Industrial Strength Records.

      I absolutely love this 12", "Bacteria" and "Gas Mask" are so distinct sounding and epitomize the Virus sound in the late '90s. These tracks had a real identity and character when they first came out, I still can't believe that they were made. Weird, funky, and technically amazing, this music is due for a resurgence.

        What an amazing record. This one has stood the test of time.

          Perfection. The bassline in gasmask just never gets old. The whole track is just masterfully creepy and gathers attention like nothing else. Its very well thought through musically, and the sounds are punchy, thick and yet soft and pleasing to the ear..

              Still think Bacteria sound more like a gas mask, and Gas Mask sounds more like bacteria multiplying. Unique sounds from producers who have not yet managed to live up to their legacy. I await the day they break their original hardware out again and start making more techstep!

                i bought the vinyl back in the release days 2 times. one for spinning in the club and the other for "NEVER" touching. both tracks are the best "MASTER PIECES" in history by Ed Rush & optical. The only confusing is: wrong labels on both sides. i thought a long time, Gasmask is Bakteria and backwards :D

                  Labels are backwards on the repress that I have.

                    This release was so unique for its time. I reckon the vinyls are getting tricky to find these days, especially with the plates the right way round!

                      "Bacteria" is one of the tracks that got me into drum & bass. Back in the days of 1998, it was hard to tell what really was sick and what sucked when you were wet behind the ears and ignorant to the traits of a top producer. However, there are always those tunes where it's blindingly obvious they are amazing, as they grab you immediately. "Bacteria" was one of those tunes for me, along with "Hard Noize" by Dillinja and "Turbulence" by Moving Fusion. Produced during Ed Rush & Optical's golden years, "Bacteria" was the apex of their sound. The intro is superb and unconventional, the drums unmistakable and the synth lead is unlike anything I've ever heard.

                      "Gas Mask" is an unorthadox creeping track with a dark character that really gets going 2/3 of the way through. For the time it was highly original, and although harder to get than "Bacteria", it was clearly spawned from the minds of two brilliant producers.

                      The stickers were the wrong way around for some time, so for years people thought the tracks had different names, although I always preferred the name "Gas Mask" for "Bacteria". The artwork was fairly minimalist but really suited the sound, and added to the character of the package. I always thought it looked fantastic.

                      This is a truly classic plate and essential component of any self-respecting drum & bass DJ's collection.
