“A conductor with the New York Philharmonic halted a performance due to a ringing cellphone, a rare occurrence that has sparked much talk about proper phone protocol.
As the orchestra was hitting the final movement of Gustav Mahler’s Symphony No. 9 during a Tuesday night performance at New York’s Lincoln Center, the distinct sounds of marimba music emanating from the first row was floating out.
After a hard glare from music director Alan Gilbert, the phone kept ringing, at which point Gilbert stopped the performance altogether.”
