Wow, this was a nice discovery. I wasn't up on Imogen Heap, but this youtube clip of her making awesome for 103.1 FM (apparently) is pretty cool.
Besides being a wonderful introduction to an artist, I like this clip because it's a great example of the music-making process creating wonderful content. Even if the song isn't your cup of tea, the first couple minutes watching her create something out of nothing are still compelling.
All new artists should be recording video footage of them making their music if at all possible. There's little downside to having the clips to play with, and a little video demo like this might give a track that extra oomph in connecting people with your music. I'm all about Imogen Heap now, and it's because of this clip.
