If you're talking about SAVAGELY INCLINE...
Well, assuming that it exists, it's probably a "recorded, but not released" deal (like King Tee's THY KINGDOM COME, which Dre ultimately decided not to put out back in '97, although Frisco Street Show sold it last year)--it was advertised as far back as JT's SOMETHING CRUCIAL (which was from 2000).
I'd like to hear Ive Lowe on a solo, though--he had some nice verses on "Millionaire Pirates", "The Other Side Of The Game 2" and "Exclusively" (from JT's HUSTLE RELENTLESS).
PEACE!
