Pop Evil recently hit the studio to lay down some acoustic tracks and ended up recording a very not-acoustic track called 'Unstoppable' -- check out the song and the new lyric video here.

The new song will be included as one of two bonus tracks -- along with the acoustic version of 'Monster You Made' -- included on the deluxe edition of Pop Evil's 'War of Angels.' Frontman Leigh Kakaty explains how the 'Unstoppable' came together:

"We recently had a break from the road to go into the studio with Johnny K. We knew we wanted to release these tracks soon so our fans would have something to kick off the new year! They deserve it, they've been there for us through the thick and thin! 'Unstoppable' is about the obstacles we dealt with as a band during the past year. Going through a six month battle with our former record label and the loss of our drummer were both stressful for us as a band. Despite these obstacles, we still managed to overcome them all while playing over 200 shows this year!"

The iTunes Deluxe Edition of 'War of Angels' featuring the two bonus tracks is available now.
