Against his doctor's advice, Armstrong played a two-week engagement in March 1971 at the Waldorf-Astoria's Empire Room. At the end of it he was hospitalized for a heart attack. He was released from the hospital in May, and quickly resumed practicing his trumpet playing. Still hoping to get back on the road, Armstrong died of a heart attack in his sleep on July 6, 1971, a month before his 70th birthday.
