Every time I listen to Aes Dana - Leylines, I fall in love again with this album!
It is monotone, for others boring, but somehow it has a tribal, trancy feeling... I LOVE it! Who can tell me more names of technoid 'powerful' ambient I know Biosphere has some releases like that as well, and Evan Bartholomew - Secret Entries into Darkness I LOVE as well (same vibe)
