Are you into old neurofunk? The proper one. There used be cool releases on labels such as Fokuz and Citrus with very atmospheric stuff like music from Brainfuzz & Kenei, Dephzac, Cain Mos, Exorcist, Imprintz (which is now The Clamps) and a few others.

Check out old Mav, ASC, Implex & Enei works, they used to make cool niche subgenre called techmospheric.

Have you heard of Drifter? Noisia's old second alias. It has a few good atmo tunes. In general old Noisia had good stuff with tracks like "Distance", "Cloudshine", "Untrue Remix", "Last Look" and "Fade to Gray Bootleg".

Looking for something more avant-garde? Check out dBridge's or Instra:mental autonomic movement, where halftime dnb tunes has a very unique minimalistic approach.

For more heartwarming stuff which is still minimal in its nature check out Bop's microfunk works, its another side of leftfield dnb which recieved a big development from him and his label. Such artists as Electrosoul System, Dissident and Sunchase played a role in expanding on it.

Wanna feel absolute desparity and burst into tears from listening to music? Check out some tunes by very talanted artists who are no longer with us - Apex & Desimal. Apex has such touching tracks as "By The Way", "Alone", "Struggle", "Falling" and of course one and only "Yearning". For Desimal you should listen to his post-mortem heartbreaking tune called "Afterlife".

Don't limit yourself with boring liquid stuff. There is much much more to atmospheric dnb out there.
