REMEMBERING MARIAN McPARTLAND: Marian McPartland, best known as the host of public radio show Marian McPartland’s Piano Jazz, died last week at the age of 95. She influenced generations of jazz musicians, including our very own Norah Jones. “My first exposure to Marian McPartland actually wasn’t through Piano Jazz,” she tells nytimes.com. “When I was 14 or 15, my mom took me to a free concert in Dallas with Marian and her trio. I was already into jazz and going to a performing arts school. But up until then I hadn’t seen a lot of women perform jazz, certainly no women instrumentalists. And to see this lady who was my grandmother’s age up there, playing with a piano trio, was just the coolest thing I’d ever seen.”

PRESIDENTIAL PICTURES: The Sixth Floor Museum is currently hosting “The American President: Photographs from the Archives of The Associated Press.” It’s one of a handful of programs the museum is putting on tied to the 50th anniversary of the Kennedy assassination. And it sounds as if the show is a mix of familiar and lesser known images. “Some of the photos are well-known: Elvis Presley visiting with Richard Nixon in the Oval Office; Harry Truman holding up the newspaper erroneously announcing his defeat; Franklin Roosevelt clinching a cigarette holder between his teeth,” Bretney Hamilton writes on dallasnews.com. “Others are less recognizable, but amusing, such as an image of Ronald Reagan cutting in — or attempting to — while Nancy Reagan dances with Frank Sinatra.” The exhibition is up through Oct. 27.
