No, it's not a joke. I remixed "Plants vs Zombies" main theme to be super-epic orchestral stuff with distorted guitars. More like an experiment, but a very serious experiment, to see how a tune can change when you go orchestral, then distorted guitars, then even harmonize your own way without checking what the original chords were.
Main tools used here were Spitfire Audio Originals Strings and Brass plus Native Instruments Electric Sunburst, Drumlab and Kinetic Toys for the melody.
That was fun.
