Paul Kantner, one of the giants of the San Francisco music scene, died Thursday. Mr. Kantner, a founding member of the Jefferson Airplane, was 74 and had suffered a heart attack this week. His death was confirmed by longtime publicist and friend, Cynthia Bowman, who said he died of multiple organ failure and septic shock. Mr. Kantner had a string of health problems in recent years, including a heart attack in March. With Jefferson Airplane, Mr. Kantner pioneered what became known as the San Francisco sound in the mid-1960s, with such hits as “Somebody to Love” and “White Rabbit.”
