I'm re-posting this from another meetup so I'm hoping the information is accurate. They did this master class last year and it was quite the experience watching the quartet work with the students. Not to be missed.
World Famous Classical String Quartet - A chance to experience them for free.
Free - Tuesday the Quartet will conduct a Master Class for professional music students. It's outstanding to hear them instruct and give critques to students, and sometimes they just perform as example. That can be extraordinary. After all, they really are one of the best Quartets in the world. No Bull. This event is scheduled in Lincoln Hall Peformance Venue, 75, which is the Basement/Lower Level Performance Space. I suggest getting there between 11:30 and 11:45. Seating is not reserved for the Master Class but those of us getting there early should be able to reserve a number of seats. Event ends at 1:00 PM.
