The West Virginia Symphony has been in debt since the moment it moved into its new home at Charleston’s Clay Center three years ago, and the orchestra is hoping a major endowment drive will plug the seemingly permanent hole in its finances. The WVS’s accumulated debt stands at nearly $800,000, with $640,000 more on various credit lines. Worse, the orchestra’s subscriber base is less than half what it was a decade ago, and cuts to the musicians’ roster and the season schedule have done nothing to alleviate the problem.
