Elvis Presley was born in Tupelo, Mississippi in 1935 and became one of the most important figures of 20th century popular culture. He helped develop rock and roll music by blending pop, country and R&B styles. Some of his most famous songs include "Viva Las Vegas", "Memories", and "Always On My Mind". Presley was a sex symbol and icon of heterosexuality who sold over 1 billion records globally, though his career and life were cut short when he died of a heart attack at age 42 in 1977, likely due to long-term drug abuse.
