Wrathbone may be a fictional metal band, but their music is the real deal.

Before we rolled a single camera, we created five original songs inspired by the gloriously excessive sounds of the 1980s. Four hard-rocking metal tracks for our heroes, and one irresistibly catchy pop anthem for their arch nemesis.

In the second installment of my behind-the-scenes series, I'm sharing how we made the soundtrack, from my earliest GarageBand demos to collaborating with an incredible team of musicians in Nashville and LA.
