Brad Mehldau gave the New York premiere of his Highway Rider in Carnegie Hall's Zankel Hall Tuesday night, performing with the St. Paul Chamber Orchestra and the musicians featured on the album. The New York Times says of all Mehldau's classically inspired works, Highway Rider "is his grandest effort yet," with its "ear-catching modal motif" and influences in Beethoven. At the same time, it remains "couched in jazz’s bluesy chromaticism and fluid rhythms." Highway Rider's European premiere is this Saturday at the Barbican in London.
