Unfortunately, It looks like this is not a hoax... Guru of the venerable rap duo Gang Starr is in a coma, following a heart attack, according to his sister. Hip Hop DX confirmed that the veteran emcee is in critical condition. According to longtime partner DJ Premier, Guru will undergo surgery on Monday. Hopefully he will be okay. Even though Gangstarr split in 2004, Guru remains an important figure in hip hop. We want him to hang around a long time.
