Sarah Slean has made eight albums, the latest of which is a double album, Land & Sea, featuring original scores composed for a 21-piece string orchestra. She hasn’t brought quite that many musicians with her to TEDGlobal but together with the local Cairn String Quartet she starts off with a quiet piece for piano, a string quartet and her own magical voice. Then she kicks off her gorgeous red high heels (“they were just for show”) and skips to the front of the stage to perform her composition “Lucky Me.” Indeed, lucky us.
