When Turnstiles hit shelves in the spring of 1976, Billy Joel was looking dangerously like a one-hit wonder. "Piano Man" was three long years in the past, and his subsequent releases all stiffed. "Summer Highland Falls," one of the standout tracks from the album, nicely sums up his emotional state at the time. It was a period of highs and lows – or "sadness and euphoria," as the song states. It's a beautiful song that Joel has often cited as one of his favorite all-time compositions. Even the piano intro is wistful. The best version of the song is found on Billy's 1981 live album, Songs in the Attic.
