Some of my favorite music covers on Youtube are the acoustic ones where the artists use only their vocals to cover the song (the instruments are all done vocally). Check out some great ones like Pentatonix, or Mike Tompkins!
Well, I unfortunately don't have the vocal talent to do that, but if I did, I'd definitely use Gridplay to record my videos. You can create videos in separate cells for a dynamic film. And this can work for anything, from making a multi-angle display of your skateboard skills, to sending a more interesting... 'romantic' video to your partner. Today this great app drops from $1.99 to FREE!
