The Philadelphia Orchestra has chosen Canadian conductor Yannick Nézet-Séguin, 35, to become its eighth music director.

Under the appointment expected to be approved by the orchestra's board Monday, Nézet-Séguin will have the title of music director-designate for the next two seasons, formally taking over in the fall of 2012.

Chief conductor Charles Dutoit will become conductor laureate then.

The contract runs through 2017, but board chairman Richard B. Worley said he hopes the conductor will remain for a decade or longer.

Worley said he believes the orchestra has "attracted a rising star early in his career," which will help build audiences.

The offer came after came after Nézet-Séguin had made only two visits to Verizon Hall in 2008 and 2009.

The French-Canadian conductor has been riding a wave of acclaim recently, winning much praise for his Metropolitan Opera debut earlier this year in the company's new production of Carmen in New York.

Nézet-Séguin also serves as music director of the Rotterdam Philharmonic Orchestra and principal guest conductor of the London Philharmonic Orchestra while continuing his long-term gig as artistic director and principal conductor of the Orchestre Métropolitain du Grand Montréal.
