The popular band Backstreet Boys will broadcast its upcoming concert live on Yahoo, the second time the group has teamed up with the Web giant. The concert will be broadcast live Friday at 5:30 p.m. PDT from the American Airlines Arena in Dallas. The Webcast will be produced by Yahoo Broadcast, the company's multimedia Web-streaming service. The Backstreet Boys and Yahoo collaborated in a similar event in March. Yahoo has also teamed up with other bands to promote upcoming albums or to allow fans to listen to albums before they are released.
