Composed by Hans Zimmer and Klaus Badelt.
This type of music is what made me fall in love with Hans Zimmer's work, more than 10 years ago when I discovered the expanded musical world of Pirates of the Caribbean. Such fun, simplistic, actiony yet melodic tracks can only be found in a couple scores (than I know of) -- Pirates, Gladiator, Rango, The Lone Ranger. I would never have thought that such a gem would be hiding in a score that I thought I already knew (and liked a lot!)...
Thanks to Stéphane Humez from the HansZimmer.com Facebook page for the find. Enjoy!
