Gates of Thunder for the NEC CD systems (Turbo Duo / Duo / PC Engine CD / TG16 CD).
Hit up
https://www.youtube.com/watch?v=EH5LUTlTIBA and skip forward to 32:44 however there's good stuff across the board to be found in there.
Lords of Thunder had great music as well.

Skip to 38:07 like is suggested in the comments there. 11:18 is the beginning to a nice, heavy, angry track.
Of course YouTube doesn't do these justice compared to a CD.
It's a total fuckin' shame the masses never got to enjoy such splendor.
I was rockin' out to this stuff through my stereo system while most people were listening to blips and bloops on SNES & Genesis (both of which I too had)
Quite fond of Final Fantasy music in USA FF2 & FF3, though, as far as cartridges went at the time.
