what exactly month for this anniversary?!

On October they signed at XL.
First gig was on February in Labirynth.

Labirynth gig was on February 1991 ? I thought that was on christmas 1990.
On october 1990 Liam signed only singiel What Evil Lurks which was released on february 1991 ?

On February, it's sure. And even it was in 1990. Source: http://www.theprodigylive.es/ and many many interviews.
WEL was released on Feb 1991, yep

this will be a cool day, 20 years of amazing tunes and there still getting better.

it would be cool if liam released some type of song on the website to celebrate the 20th year but i doubt it.

still its always worth the wait.

I want a 20y anniversary singles boxset. with some xtras

waste of money, will download it from piratebay
need a new material

+1

A new album released on that date.

are you crazy or dreamer ? Wait for 2012, maybe 2013. not earlier. ... and don't trust what Liam say about new album date.

Oh my god !!! 20 years When i'm conscious of this i can't believe that Prodigy is so much time long. It's full of time of my life, from even my childhood. They are dinosaurs of techno. in their music i don't hear that. Liam is almost 40 year old man he doesn't look for his 38, much younger.
They must celebrate for some way this 20 year anniversary. Maybe special gig, effects on any gig, new video, dvd... they've got a fantasy in this matter. i don't expect new material only one year after new album -IMD, i'm a realist.... maybe one new track for celebration would be realistic if they really started this in the studio.

a new age optimist.
have faith

Optimism makes life happier but our experience tell us that in our times Prodigy release albums in 5-7 years time break so 3 years of waiting untill 2012 is for me optimistic variant
...and really must to learn..... don't trust what Liam says about dates of album. Waiting for AONO and IMD albums was lesson of this.
Prodigy is not a Madonna that can make album every year. Prodigy is real music art and like piece of art creation of this must last much longer.

but Liam Howlett can always suprise us.

Maybe they will do something special for the 20th anniversary. Maybe a huge gig, maybe the biggest solo show they've done. Maybe they'll attract 50,000 people to it.

Maybe it'll happen, who knows................

Ah you said it already
