Eric Lewis, an astonishingly talented crossover jazz pianist — seen by many for the first time at TED2009 — sets fire to the keys with his shattering rendition of Evanescence’s chart-topper, “Going Under.”Eric Lewis channels the raw emotion of alternative rock into fiery, take-no-prisoners jazz piano arrangements. Before setting out to capture the voice of alt rock in the keys, he toured with the likes of music legends Wynton Marsalis and Elvin Jones.
