On her first album with original songs in nearly 20 years, Carly Simon is still working on some old demons and still determined to outlast them. Simon announced last month that she had been diagnosed with Parkinson’s disease while recording “Comes in Waves,” and that she also had surgery to remove a cancerous skin growth. “Comes in Waves” includes a remaster of Simon’s decades-old political song “Share the End,” and elsewhere echoes moments from her previous records. Her musical journey has always been personal, and longtime Simon fans are the most likely to enjoy catching up with her. ___“Comes in Waves,” by Carly SimonThree stars out of fiveOn repeat: “Love the Way I Do,” “Four in the Morning”Skip it: “Share the End”For fans of: Carly Simon, most of all, and of pop torch singers in general.
