Thanks for the extra tunes you've been able to ID, I'll let you know if I can find any more.
I've found the two you were asking about, plus one more:
Grooverider / Andy C
You were right about this being by Danny C, it’s:
B2) Twisted Anger Feat. Danny C – Say Yeah [Dread – The Cracked Planet EP]
(is this also the tune teased over A11?)
I've also managed to ID the tune teased at the very end of Grooverider's set:
B5) DJ Zinc – Casino Royale (Remix) [True Playaz – Present Tense EP]
>> Drumsound & Simon ‘Bassline’ Smith – Breakdown (Twisted Individual Remix) [Technique – The X Project Pt 3]
Grooverider / Adam F
A4) Arthur L – Moomjy (A-Sides Remix) [Unreleased]
(I own this on dubplate: I messaged A-Sides a few months ago and he said the original tune was by Arthur L from New York, but I can't find any more information on Arthur L or a tune called "Moomjy". See the note I've added to the Discogs entry: https://www.discogs.com/release/28998661-Unknown-Artist-Undercover-Agent-Moomjy-A-Sides-Remix-Oh-Gosh-A-Sides-Remix).
A6) Alpha Omega – Feedback [Invader]
(Grooverider played this at Best Of British, ‘The Jubilee Jam’ the week before he played at Code, maybe this was where you had heard it before?) https://www.mixesdb.com/w/2002-06-02_-_Grooverider_@_Best_Of_British_-_The_Jubilee_Jam,_Rex_Music_Arena,_London
B10) JB – This Style [Back 2 Basics]
Adam F / Mampi Swift
A2) Shy FX – Wolf (Dillinja Rmx) [Ebony Dubs – Volume 1]
>> ?
I've not been able to ID this tune, but Dangerous D plays it in his set at Accelerated Culture @ Code Part IV (A3) "flavour, flavour, flavour" https://soundcloud.com/scuzzy983/accelerated-culture-code-part-iv-dangerous-d?in=scuzzy983/sets/accelerated-culture-code-iv
I've not been able to ID it, I've searched for tunes with "Flavour", "Flavor" and "Flava" in the title but not found it yet...
