This is the making of the music video for Hearts, a song by Dan Black and featuring Kelis. It’s a stunning demonstration of the hard work some artists put into their craft.
Black had to stand on a roof for 24 hours without a break and have a photo taken every 16 seconds during that time. He also had to sync his voice to the song.
This link will take you to the finished music video, but I actually think the “behind the scenes” view is more interesting to watch.
You should remember this clip the next time your favorite band puts out a music video which is just them performing live. Those videos are the height of laziness.
