The main introductory riff, consisting of a simple 13-note progression, is repeated throughout most of the song.
"Perhaps our most ambitious work to date, was first conceived with an instrument quite alien to Incubus and all of rock music to be precise. A 'Ko-kyu' is what was used here and it was donated by a very generous and talented man by the name of Steve Vai. One late evening we began conjuring and experimenting with this track and it quickly brought to mind the image and analogy of floating freely down a river; hence the content of the song. Our friend Suzi Katayama, who has in the past worked string arrangements with the likes of Björk, Madonna and even Yours Truly for an acoustic performance in L.A., lent her classical finesse to this story. And in doing so helped it become exactly what we envisioned; a song so atmospheric and vibratory, it would make those who listened to it doze off into a land of rivers, kung fu and unicorns, eventually making the listener pee in his/her pants."
