I posted your findings in the IC thread, but I'll repost it here for convenience.
After a few hours spent searching and sleuthing the 'Trix, you managed to find the lead you needed. Several emails were sent out to names in the music industry, each email saying the same; that "some lost tracks from a legendary dead rocker" had become available for sale. Those who responded had received a follow-up naming the dead rocker: JetBlack. Luckily, you've managed to trace one of them to Nabo.
You’ve heard of Nabo. Everybody’s heard of Nabo, unless they live under a rock. The whole Orxploitation movement has settled down somewhat in the last five or six years from its former white-hot glory, but that doesn’t mean it’s going away anytime soon. Every few months the music-sim companies find somebody new to promote, propel up to the pop charts, and exploit until they can find a new cash cow. These days, Nabo’s their golden boy. Anybody who pays attention to popular music knows his story: he’s an ork ganger kid from the Seattle Barrens who loves music more than he loves firefights and selling BTLs. He makes a name for himself performing in small local clubs, gets noticed by somebody big time, and the next thing he knows he’s rocketing up the charts and livin’ la vida loca. Must be nice.
And Mirikon has some further information, but the stuff he knows can easily be found with a quick search.
