Pinetop Perkins, the boogie-woogie piano player who worked in Muddy Waters’s last great band and was among the last surviving members of the first generation of Delta bluesmen, died on Monday at his home in Austin, Tex. He was 97.

His death was confirmed by Hugh Southard, his agent for the last 15 years.

From his days in the groups of Waters and the slide guitarist Robert Nighthawk to the vigorous solo career he fashioned over the last 20 years, Mr. Perkins’s accomplishments were numerous and considerable. His longevity as a performer was remarkable — all the more so considering his fondness for cigarettes and alcohol; by his own account he began smoking at age 9 and didn’t quit drinking until he was 82. Few people working in any popular art form have been as prolific in the ninth and tenth decades of their lives.

Billy Taylor, a pianist and composer who was also an eloquent spokesman and advocate for jazz as well as a familiar presence for many years on television and radio, died on Tuesday in Manhattan. He was 89 and lived in the Riverdale area of the Bronx.

The cause was heart failure, said his daughter, Kim Taylor-Thompson.

Dr. Taylor, as he preferred to be called (he earned a doctorate in music education from the University of Massachusetts at Amherst in 1975), was a living refutation of the stereotype of jazz musicians as unschooled, unsophisticated and inarticulate, an image that was prevalent when he began his career in the 1940s, and that he did as much as any other musician to erase.
