I spend an awful lot of time doing fairly mind-numbing work at a computer, so I am always looking for good sources of interesting things to listen to. I've really been digging on the Creators at Carnegie series on NPR. The Caetano Veloso/David Byrne concert, the kd lang concert, and the Emmylou Harris concerts really stand out in my mind. They just put up the Magnetic Fields show on the website and I am listening to it right now.
NPR : The Magnetic Fields in Concert
I've only seen them live once (although I have seen Stephin doing wrong word kareoke on more than one occassion), but it was really nice hearing some of the songs without all the synth. Nothing against the synth and production on the albums, but naked songs are nice every once in a while.
