What is the OST playing in Naruto Shippuden Ep 42 where Four-tailed Naruto fights Orochimaru I'm interested in finding the OST at the 9:05 minute mark in this particular video

I've searched on Youtube, but can't find anything.
It sounds like an unreleased variant of Dark Clouds (Shippuuden OST 1 track 20). There's an unofficial version here, titled &quot;Dark Clouds (other Verison)&quot;.
(Same as in this answer.)
