Ladies and Gentleman, here is a scoop straight from Greg Mercer, check out NPR Music: All Songs Considered. It's a neat portal on up and coming bands that have appeared on NPR recently, but the real gold mine is the Podcast link to the right of the page. NPR is publishing concert podcasts so you can listen to them on your Ipod or other music playing device (are there any others?). The whole concert, live and sounding good. Wow.
I'll be listening to the New Pornographers, or maybe Andrew Bird. Wait, what about Death Cab, or the Yeah Yeah Yeah's, or Spoon. Options abound!
