Music Group Plans to Convert Office Building to Harp

PHILADELPHIA – A trio of musicians is turning a new office building into a gigantic harp for a rather unusual grand opening celebration next week.

String Theory, a Los Angeles-based group, plans to attach a dozen 100-foot-long brass wires to the 29-story Cira Centre building next to Philadelphia's main railroad station.

The group has turned concert halls and a whole 52-story building into musical instruments in the past.

"Every space has its own sonic character," said Luke Rothschild, whose wife, Holly, will play what he installs at the grand opening Thursday evening.

Rothschild said he expects the Cira Centre to make a lively instrument because of the amount of metal and glass in the structure.
