The 125th season opens on May 4 with a gala concert featuring multiple Tony Award-winner Idina Menzel and the inimitable Doc Severinsen, who holds the distinction of having performed under the batons of Arthur Fiedler, John Williams, and Keith Lockhart—a perfect addition to a program honoring the leadership legacies of the three most famous Boston Pops conductors. During the season the Pops will present the world premiere of a new work in honor of the Kennedy brothers, mark the 10th anniversary of the popular radio and TV show "From the Top," focus on esteemed artists from the fields of jazz, musical theater, and pop, including Dave Brubeck, Kelli O'Hara, and Maureen McGovern, and honor the legacies of such musical titans as Ray Charles, Duke Ellington, Cole Porter, and Rodgers and Hammerstein. Daniel Bernard Roumain, who in concert melds his classical music roots with his own Haitian-American cultural references and vibrant musical imagination, and Ozomatli, the multi-Grammy award-winning, genre-defying sensation, join the orchestra for programs that continue the Pops tradition of focusing on the best and brightest new talent on the musical scene today. Returning to the Pops schedule is the legendary film music series under the direction of John Williams, this year marking his 30th anniversary with the Pops, and one of the newest Pops traditions, Gospel Night with Charles Floyd. To bring the 125th season to a close in June, the Boston Pops will present one of this country's greatest living legends—the incomparable Arlo Guthrie.
