Antoine "Fats" Domino, a pioneer of rock n' roll, passed away Tuesday this week at the age of 89. According to the Jefferson Parish Medical Examiner's office in Louisiana, the musician passed away due to natural causes. Domino cut a string of famous songs in the 1950s and early '60s such as "Ain't That a Shame," "Blueberry Hill" and "Blue Monday," which helped make him one of the music's leading figures. Over his career, he also helped establish his hometown of New Orleans as a rock 'n' roll hotbed. Domino, who was inducted into the Rock and Roll Hall of Fame in 1986, remained a steadfast part of the New Orleans music scene up until his passing.
