Cold Case Files: Vol. 1 is a compilation album by American hardcore rap group Onyx released on August 19, 2008, by Iceman Music Group. This compilation contains singles and lost studio recordings from the group's albums.

The album was produced by Jam Master Jay, Fredro Starr, Kronic Tones, Dominche, Self and Keith Horne. The album features guest appearances from Method Man, X1 , Panama P.I., Smoothe Da Hustler, Trigger Tha Gambler, D.V. Alias Khrist, All City, Still Livin', Gang Green, Whosane and Chocolate.

After conquering Hollywood, Onyx return to the scene, emerging from their musical vaults with a new album, Cold Case Files, a 16-track collection of previously unreleased songs executive produced by the members of Onyx and Omar "Iceman" Sharif. The collection features underground singles, lost studio recordings from the group's first three albums, and appearances from Method Man, deceased Onyx affiliate X1, and Gang Green. According to the group, revisiting these sessions also served as a tribute to fallen soldiers Jam Master Jay, X1, Big DS, and all Onyx affiliates who have passed away in the last five years; some of which are still unsolved murders.^[1]

Fredro's younger brother, Whosane, archived most of the unreleased tracks. Sonny Seeza, who served as album supervisor shares, "Whosane was usually in the studio with us and kept all our classic recordings that never made it onto albums in the Onyx music vault; so when the time came to select tracks for Cold Case Files, he had tracks that we didn't even know existed on everything from cassettes, DATs, CDs to 2-inch reels.^[2] According to Fredro Starr, Onyx has at least 60 tracks, and this is just the first volume of unheard material.^[3] DJ Infinite, one of Fredro's good friends, came up with the idea to make this album:^[4]

"...We wanted to put something out for the fans, especially the true Onyx fans. DJ Infinite, one of my good friends and associates came up with the idea of doing this album and putting out some of these tracks. So my brother Whosane had the cassettes and the DATs saved from back in the days and we just transferred all that into the digital age and now you got the Cold Case album."

RomanCooper of HipHopDX gave the album three stars out of five, saying "...This album is easily worth copping – if you’re an Onyx fan. If you’re not familiar with their music, you’d be much better served scooping up either Bacdafucup or All We Got Iz Us. Cold Case Files doesn’t really manage to distinguish itself from common issues associated with compilation albums. That being said, even cuts that didn’t make Onyx‘s albums manage to bring you back to the gritty early 1990s. With a gem or two nestled among these tracks, fans of that sound may want to check this."^[11]

Cold Case Files Vol. 2 is a compilation album by American hip hop group Onyx released on August 10, 2012 by Major Independents.^[14] Physical copies became available on January 23, 2014.^[15] The album contained unreleased tracks from the group's first three albums, Bacdafucup, All We Got Iz Us and Shut 'Em Down.

The album was produced by Keith Horne, Onyx, 8-Off Assassin, 3rd Eye (a.k.a. Jesse West) and Jam Master Jay. The album features guest appearances from Naughty By Nature, Biggie Smalls, 3rd Eye (a.k.a. Jesse West), Gang Green (X1, Sife, Still Livin'), All City (Greg Valentine), Jared "Choclatt" Crawford и Tracy "Sunshiine" Woodall.

One of the main findings of this collection was the never released before track "Flip Dat Shit". In January 1993, at the recording studio The Hit Factory in NYC, rappers Naughty By Nature, Onyx, Chyskillz, Jam Master Jay, Biggie Smalls, Puff Daddy and producer/rapper Jesse West (also known as 3rd Eye) joined together to record a track "Flip That Shit" special for the soundtrack to the new movie "Who's the Man?". Many years later, fans were still able to hear the track "Flip That Shit" thanks to DJ JS1, who passed this digitized tape to Sticky Fingaz, who added this track to the collection of unreleased songs of Onyx's "Cold Case Files Vol. 2"

The track "To All Ya'll Crews, Whatever", which was not included on the album "All We Got Iz Us", was leaked on Onyx's website in CD quality on March 22, 2016. Earlier, this track was released on Cold Case Files Vol. 2 in poorly digitized cassette quality.

BOOM BAP REVIEWS gave this release a good response saying "The important thing is that Onyx actually took the bold step and we're here now with yet another Onyx collection that appealed. So, is it any good? The very nature of this project should be a godsend to Onyx fans. Plus, for the assholes out there, they're simply telling you to buy it for free. And besides, 6 crap songs out of 16 is still a bargain, right? Right?!".^[19]
