Tim Ray is a member of the Steinway "family" and endorses Steinway and Sons pianos. He has been on the Steinway artist roster since 2005 and has been playing Steinways for most of his life.
His current favorite piano is the one he has at home - an American Steinway model B, circa 1979. It was restored in 1997 (mostly to replace the teflon bushings with the more traditional and reliable felt bushings), and now it plays and sounds like a dream. You can hear it on Tim's new solo piano recordings "On My Own vol. 1 - New Works" and On My Own vol. 2 (coming soon).
