Banjo-Kazooie was released for the Nintendo 64 in June of 1998. It was developed by Rare and the original soundtrack written by long-time composer Grant Kirkhope. There has never been a commercial release for the Banjo-Kazooie Soundtrack but back in 2014 on Grant Kirkhope's Bandcamp page, you were able to pay any price and download the massive 164 track collection of music from Banjo-Kazooie. Unfortunately—I believe it was in 2016—the page was removed and you could no longer purchase and download the classic tunes. I downloaded the release in VBR MP3 but I read that the FLAC version that was once available is lossy sourced, I can't confirm since that isn't the format I downloaded at the time but thought I'd mention it in case somebody was curious about a lossless version of this album.
The quality of Everything and the Kitchen Sink is very good. High db, no crackling, muffling or distortion. Everything you'd expect from, what I assume are converted straight from source files - considering it's from Grant Kirkhope himself. It's an apt title considering that this album contains.. well, everything. Every musical note you could imagine from Nintendo 64's Banjo-Kazooie is included. Variations of Freezeezy Peak, Gobi's Valley Mad Monster Mansion, Click Clock Wood, Gruntilda's Lair, It's all here. As well as the mutiple fanfare cues and unused beta tracks.
Banjo-Kazooie: Everything and the Kitchen Sink! is uploaded in MP3 format and you'll find it in the archives. Enjoy!
