Musician Gil Scott-Heron, who helped lay the groundwork for rap by mixing together percussion with spoken-word poetry and political expression, died Friday at 62.

Heron is most known for his song, "The Revolution Will Not Be Televised," from his mid 70's album 125th and Lenox. He sometimes called his music Bluesology or Third World music, and he had been called the Godfather of Rap, a title he rejected.

Gil Scott-Heron's most recent album was "I'm New Here," which he started recording in 2007 and released in 2010.

Doris C. Nolan, a friend who answered the phone at Heron's Manhattan recording company, said he died Friday at St. Luke's Hospital after becoming sick upon returning from a trip to Europe.
