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.

These two tracks are the first drum and bass songs I ever heard and I've been hooked ever since. They still remain two of my favourite tracks :D
If you've never listened to them, go do it now!

Amazing tune, first one i ever bought for the purpose of mixing :)

'Bacteria' is absolutely awesome. I love the doomsday intro and the twisted bass is a joy to listen to. One of my fav dnb tunes off all time from the masters of tech dnb. This is also a joy to mix with and i fondly remember when i first picked this up, i had been after it for ages!

'Gasmask' is a worthy flip tune too with nice atmospheric and a sick rolling bassline. Both tunes are excellent and this is a must have 12" for any fan of the classic Virus sound.

The greatest drum and bass 12" ever created? Well it's up there right with Roni Size's 26 Bass/Snapshot. Absolutely amazing stuff once again. Such an important milestone in the development of the genre puts it up in the top ten most important drum and bass plates ever.
