Dj 50 grand produced notorious b i g s demo tape dead at 55

I think there may be some misinformation here.

DJ Premier, not DJ 50 Grand, produced The Notorious B.I.G.'s demo tape, "Ready to Die". And, unfortunately, The Notorious B.I.G. (Christopher Wallace) passed away on March 9, 1997, at the age of 24, not 55.

DJ Premier is a renowned hip-hop producer and DJ, known for his work with Gang Starr, among others. He produced several tracks on Biggie's debut album "Ready to Die", including "The World Is Yours" and "Unbelievable".

DJ 50 Grand, on the other hand, is not a well-known producer or DJ in the hip-hop industry. It's possible that you may be thinking of a different artist or producer.

Let me know if you have any other questions!
