The value of this record rocketed more recently having been id'ed in one of Nina Kraviz mixes, typical early Aphex Twin stuff - bleepy, acidy, trippy call it what you want it plays with your mind!!.... is it just me or can you hear the sounds on this release in alot of Paul Birkens releases? just shows you the roots of alot of modern day techno/electro, hunt down at all costs you won't be disappointed ;)

funny enough my version of this record hasn't got The Aphex Twin stamped on it, but my Blue record does.
Bought it as a double 12" new in 1992/93 in Amsterdam.

I got this EP as a gift with an order from Warp, some years ago.

The label does not have the 'THE APHEX TWIN' stamp, but a strange sticker and some handwritten text: "PHILIE K'S ACIEED" on the A-side and "REDSIDE" on the reverse side.

(Not kidding about it being a gift from Warp; they used to give more stuff away, probably stuff they had lying about?).

The best 12 of the Indicator series. Acid house that squeaks, squelches, blips and bangs your head till you submit. The last tune on the B side has a perpetual groove; and some of the tunes will be missed if you blink. More power to Rephlex.

I met RDJ in late 2000 and asked him what Universal Indicator tracks were his. He answered: "half the tracks on the red one". I was surprised he didn't mention more. I asked: "nothing on the green one ?" since it is the most Aphexy-sounding to me. And he replied: "no... the red one". Maybe he was just messing with me, but 6 months ahead, he told me about the creation of his new MEN label (which came true) and confirmed the existence of the Q-Chastic double-12" with no plans to re-release it. This is what he said to me. What you believe is now up to you ! :)

Just noticed a strong hint on the alias <i>Martin Tressider</i> today. If you examine the sleevenotes for the original 12" release of AFX - Analogue Bubblebath vol.3 (picture here at Discogs), you'll notice a very interesting text:

"Places of interest in Cornwall:
Porthoustock Quarry - The deserted home of the fabelled pirate, <i>Martin Trezidder</i>. Some say that his screams can still be heard on the cliffs at full moon."

After this solid clue, I can only conclude that Martin Tressider is definitely an alias for Richard D. James.

Comparing the red and the blue ep's. The red ep is the one really worth getting your hands on. The blue ep shows some signs of development towards the recognizable Aphex style with some of its chord progressions and the keys being used. The red one is where the freak out ear your head tracks are located.
limited to a 1000 copies hand stamped.
Made at Llannerlog (richard's studio) -undiluted
As with the blue ep, these tracks were reported at the time of their release (93) to be older tracks from the back catalog circa 88-89.
