LA-eX, featuring ‘American Idol’ alum Antonella Barba, are out with the music video to their dubstep remake of ‘Mercy’ by Kanye West. “Yo this is Antonella, and when I was fortunate enough to be on tour with Kanye in Australia, I heard ‘Mercy’ and it blew my mind,” Barba writes. “I knew right then we had to do our own LA-EX version with a little dubstep flavor. Bump this in your car & turn it up loud. This bass is for you!” Watch it via YouTube below.
