2 hardcore gabber track to id please

hello, i'm looking about the label / artist of this 2 tracks please :

"Extrait 2" comes from a set by dj david x (french hardcore dj) and the set was made in 98 or 99 i think but i don't have idea of the year of this release, it's surely a dutch track but none idea of the artist or the label

"Extrait 4" comes from a mix of 30 minutes by dj radium made in 99 i think too, none idea of the year of the release too (i think near 99 maybe but not sure)

I have ask to many peoples for identify this 2 tracks but nobody's find what are they so thanks by advance if anybody know what is it !
