Last year, the Nashville flood unfolded endless horrors. Not least among them was the realization that Soundcheck downtown had fallen victim to the rising waters. As a storage facility for some of country’s top acts, it contained priceless musical instruments that each told some small part of Music City’s history. Today, they find a perfect way to turn tragedy around with the ReTune Nashville Anniversary Celebration. The title of the event captures its optimistic tone: Who celebrates that kind of loss? Artists, apparently. Flood-damaged instruments were donated by musicians, including the likes of Keith Urban, and a talented gathering of Nashville artists transformed them into works of art. Local favorites, including Brother Mel and Herb Williams, chipped in. This fundraiser includes musical performances, a songwriters’ round, and auctions to help ReTune’s mission to benefit uninsured musicians.
