I generally don’t keep up with the portal wars, but a co-worker pointed me to MSN’s Music in Concert section where one can enjoy live concert footage, including The Bravery’s Friday afternoon set at La Zona Rosa during South By–a show I attended and wrote about.
MSN is also offering live concert footage from Stephen Marley, Pink, Gomez, Elton John, O.A.R. and several other acts. I had to switch over to Firefox (from Safari) to get the popup viewer to work, but it was worth the extra clicks.
