The Philadelphia Orchestra refuses to let the night be ruined after an unexpected cancellation of tonight’s “Pops Up” New York performance for the Carnegie Hall Opening Night concert. Instead, music director Yannick Nézet-Séguin and the rest of the ensemble will stick around for an unscheduled appearance at the Kimmel Center’s Verizon Hall. The free, nonchalant event starts at 6:30 tonight with general admission seating. Come early to Commonwealth Plaza to participate in a “Conduct the PO” pre-concert event beginning at 5:30 p.m., where concert-goers can try their hand at conducting select musicians of the Orchestra. Yannick and some of the musicians will also be autographing the new Deutsche Grammophon CD of Stravinsky’s Rite of Spring. Details can be found at Below, watch another pop-up concert the orchestra perfomed this year – mid-flight from Beijing to Macao on their tour of China.
