Jewelleo the Great is Sandman's alter-ego (Jewelleo=Onyx, his real name), from what I understand disc 2 of his new album "To Whom It May Concern" will be recorded as Jewelleo the Great, if it ever gets released (it's been delayed 6 years now). The track you posted is aiight, but it's far from the best track he's got out right now. Check out "Smoke, Choke" (which he recorded 6 years ago for the new album), and also "He Came He Saw" or "MPLStP," these are all much better tracks that showcase his versatility. Now he just needs to release his damn album already.
