Pretty much anything by Alaska
Most of the stuff Seba did until about two years ago.
Nebula
Equinox
Label wise - try Scientific Wax Retro (it's a sublabel of Scientific Wax that
tends to be a bit more focused on the atmospherics.
Other labels (some of these are defunct, but the music they released should be new to you if you've mainly been exposed to Bukem's take on atmospheric DnB) - Arctic Music, Repertoire (dead now but had some lovely oldschool atmospheric bits), early Warm Communications, Secret Operations, Outsider, Covert Operations, Subtle Audio, Bustle Beats, Pressin Hard, Vibe'z, Purified Audio, Offshore, Gamma Ray, early Fokuz, Celcius, Absys.
Artist wise - Seba, Nebula, Alaska, Equinox (some Equinox anyway) Future Engineers, ASC, Method One, J Laze, Law, Drum Origins, Mav, Naibu, Amplicon,
