Guru, a founder of the pioneering hip-hop group Gang Starr, passed away yesterday, age 43, after a year long battle with cancer.

Guru, real name Keith Elam, tried to keep his cancer diagnosis a secret, but the secret came out when he was admitted to the hospital in March due to a heart attack, that left him in a coma.

Guru was an inspiration to many and he will be missed. R.I.P. Guru!
