PHILADELPHIA – Technology that allows musicians in different places to perform together in real-time was dramatically demonstrated Tuesday in Philadelphia, where a violinist and cellist hundreds of miles apart played a duet as if they were on the same stage.

More than 600 engineers, researchers and scientists jumped to their feet and cheered after the performance at the Internet2 fall member meeting at a downtown hotel.

Violinist Marjorie Bagley, on stage in Philadelphia, and cellist Cheng-Hou Lee, projected on a video screen in DeKalb, Ill., performed the tricky Handel-Halvorsen Passacaglia for cello and violin to show off LOLA.
