I posted a song called "Song to Sing the Siren", by John Frusciante (the first and second video on the top bar are of equal quality) because in The Marriage of Cadmus and Harmony, Calasso begs the question "What song did the sirens sing?" and, in a nut shell, this song is about the sirens singing to a guy, and he's basically singing this song back to them (on the surface at least). The album is called The Empyrean (meaning heavenly), and some of it's songs are pretty darn mythological.
