Herbie Hancock and Lang Lang rehearse Liszt's "Hungarian Rhapsody" at Herbie's home in preparation for a world tour. Following their 2008 Grammy highlight performance of "Rhapsody in Blue," it seemed only natural that the pair would bring their unique backgrounds to an even greater collaboration on the world stage. Expect an unprecedented tour from the Montreux Jazz Fest in Switzerland through France, Germany, the Netherlands, England, Italy and across the USA in the summer of 2009.
