tl;dr
K.H.D.N. musicians duo who started on
Zanac Neo and then made all Milestone soundtracks, they still remain for me as prime example of "true electronica" shmup music, alongside with Raiden Fighters 1-2 and Mars Matrix. Chaos Field is nearly always in my top-10 osts.

Though boss them from RF2 was close with its dark rave
NMK's Operation Ragnarok?
This one also had some crazy final boss theme.
