A classical music fan who thought the rules didn't apply to them wound up in a sticky situation when his iPhone's ringtone blared out during Tuesday's performance of Mahler's Ninth at the Avery Fisher hall. The New York Philharmonic's musical director Alan Gilbert heard the disturbance and after a few aggressive looks, stopped his orchestra partway through the final movement until the phone was silenced. Hopefully that person learned a very valuable lesson, and everyone else will remember that there's a special circle of hell reserved for those who don't mute their phone at the theater.
