Did you guys know quite a bit of Grant Kirkhope's classic N64-era Rare soundtracks and more are available on Bandcamp?  Neither did I till just now!  I do know there are quite a few fans of these games and their OSTs, and as I recall many were only available as limited edition pack-ins and what not, so it looks like pretty big news to me.

Albums available include:
- Banjo-Kazooie
- Banjo-Tooie
- Banjo-Kazooie Beta's
- Perfect Dark
- Kingdoms of Amalur DLC and boss pieces

The GK soundtrack I myself know and love Viva Pinata isn't on the list but you can still get it at Amazon on CD and MP3.  It is beautiful!

Kirkhope's Donkey Kong 64 original soundtrack now available as well.

I know his SNES Donkey Kong Country soundtracks are popular but I haven't heard much about the N64 one.  How does it compare?

I didn't like the DK64 soundtrack as much as the SNES DKC games. I didn't even like it as much as the music in the Banjo Kazooie games.
Perfect Dark is fantastic though.

My favorite N64 soundtrack by Rare (or my favorite N64 soundtrack EVER) is still Jet Force Gemini, with Tetrisphere being a close second.
