I am going to take this opportunity to express an overdue paeon of praise and gratitude. Your ability to draw these artists out without intruding or “showing off” makes for 30 or 40 minutes (Vijay Iyer was longer) of sheer delight. You and your guests most frequently are without the displays of ego that are so cloying. I have been listening to jazz for 62 years and you have helped to keep me hip and up to date. — L.R.
