i heard these 2 tunes on my local club’s – Essential’s - radioset on february 2006. so they could be known since feb/jan or earlier.

here are my recorded samples (in one of them there is a voice of lady sayin ”Eeeessssential”, ignore that) - 3 archived mp3 files: track_1 , track_1-track_2 (1st track with part of 2nd in the end ) and track_2.
quality isn't the best.. but..
