My friend Ryan has been working at a internet startup company for a few months now. They are working on several Internet television channels devoted to music, and expected to launch full-scale soon. Have a look at the rock channel: mi145.com. There are some pretty cool videos of interviews and performances of up-and-coming bands. I liked the segment about Black Lips, who I was surprised to learn are from Atlanta.
Also:the introduction from Henry Rollins is charmingly awkward.
