Pianist and singer Jon Batiste achieved fame as the bandleader on The Late Show with Stephen Colbert, appearing with his longtime working band Stay Human since 2015. Yet the native of Kenner, Louisiana, comes from a long line of jazz musicians, and he's never relinquished those roots. He can update a New Orleans jazz classic like “St. James Infirmary,” upping the energy until it becomes an explosive, gospel-driven testimonial, but his natural pop instincts can bring soulful gravitas to the ballad “Don't Stop.” His genius is erasing the lines between genres; he makes everything he touches sound fun, without downplaying his serious chops.
