This is the original from OnTheDecks.com, back in 2002. It's a full 90 minutes. Pretty sure the guy who ran the site ripped this. The id3 tag is full of abuse directed at UKGMP3s (lol), a rival group who I guess were stealing all of his rips. On the decks was a really influential website, it allowed the whole world to access what was yet to be called "grime" while it was still in its infancy.
This set was on a CD that was rotting away, so I was lucky to save it. All the media where we store things will eventually die. Putting them on YT lets other people enjoy them, and ensures they will be around for a long time.
