I have really enjoyed Imogen Heaps music since sophomore year when I first heard "Hide and Seek." I also got the chance to see her in Portland at the Crystal. It was easily one of the best shows I have been too. Not only was Imogen amazing, the two acts that opened for her blew my mind.
This was also the first time I had seen Live Looping in person. Kid Beyond, one of the openers, used only his vocal beat boxing to create songs that sounded completely techno/electronic.
Here's a great example of not only Imogen's vocal skills, but also how she uses technology to create something exceptional.
