No need to hold the cell phone in the air to broadcast your live music experience to friends elsewhere: today sees the release of recordings of two major rock concerts that took place in Chicago in the past year. We've mentioned the Wilco CD Kicking Television previously, but there's also U2 on DVD with their Vertigo 2005. "City of Blinding Lights," indeed. And, lest we forget, on a non-musical note, there's the Oprah 20th anniversary collection — although, if you're in the market, you probably know that, don't you?
