Sega Sound Team Band, were Sega's in house band in the 80's and early 90's.
Containing on keyboards Hiroshi Kawaguchi the composer of most of the tracks from Space Harrier, After Burner and Outrun, and fellow composer Koichi Namiki on guitar, along with others in various incarnations.
As far as I'm aware they disbanded around 93, but not without leaving some early 90s videos to enjoy:

Hiroshi Kawaguchi leads Sega Sound Units band [H] these days, while Koichi Namiki, formed Blind Spot with former SST band members including guitarist Jouji Iijima around 2011.
Sean Bean bored at work. Hello everyone Hope you're doing well.
Zuntata: Taito's in House Band.
This vid is from a game music festival around '89/'90, SST and others like konami's team all plaed I believe.
Worth watching for the Shimisan Solo alone.
I've never been one to think that game music only became good with the move to CDs and arranged orchestras, whether its Yuzo Koshiro banging Detroit house out of the Yamaha YM2612 FM synth in the Megadrive, or Yoko Shimomura telling us all sonically to go home and be family men.
If anything they started getting more forgettable with the move to CD. FF7 was an interesting one because they had a really limited amount of tracks per song to work with because it shared bandwidth with battle sound effects too. As such the songs are really restrained but very expressive. I will be watching some of these later for sure.
FFS. I'll try again but that's supposed to be the main theme to Silkworm. It was that and the Ninja Warriors tune that was on an Amiga mag cover or something once and my mate gave me the tunes. Fell in love with them both.
