Rapper Chubb Rock will dedicate his upcoming album to his late wife who died last year (06) after battling cancer. The New York-based rap star - real name Richard Simpson - says new album The Grown and Sexy Theory fulfills a promise he made to his wife before she passed away - and he doesn't care if it is a commercial success. He tells Allhiphop.com, "It was actually made because of a promise I made to my wife."She passed last year from cancer. It makes you not take life for granted. She was younger than me, in perfect health. "She didn't like how music was going. She was a hip-hop fan to the fullest. But she'd turn on he radio and be like 'What's this'. So I'm doing this for her. I don't care if this record sells."Chubb Rock released several successful albums during the 1990's including his self entitled album in 1988, And The Winner Is... in 1989, The Onein 1991, I Gotta Get Mine Yo in 1992 and The Mind in 1997.
