In what it's calling a Twitter first, French radio station NRJ said Thursday it plans to tweet a live private concert by pop rockers BB Brunes. "It's never been done before on Twitter," Tony Onestas, who oversees online projects at NRJ, which claims more than 100,000 followers on the microblogging site, told AFP. Fans will not only be able to watch Friday's gig being streamed in real time via Twitcam, but they will also have the chance to post their opinions and exchange views online even as the quartet performs. "In terms of quality, we have a very good camera in place and a direct link the BB Brunes' sound engineer's panel," said Onestas, as fellow NRJ executives anticipated a near-television like experience for viewers. "We are working so that, even if the final image is less than perfect, it's still right, because we don't want a product only for this who get high-speed downloads," Onestas added.
