Six years ago, the last time David Monette was our guest on Coffeeshop Conversations, we called him “Portland’s Stradivari” because the trumpets he designs and builds are the equivalent of a Stradivarius violin…and he makes them for some of the world’s greatest musicians at his shop out near the airport in Portland.He's back because he has a new book called “Calculus of Life: A Practical Guide to Transcendence.”What does that have to do with music? According to David, just about everything.He’ll be giving a talk at Portland’s New Renaissance bookstore on Saturday, May 25.On Tuesday, May 21st, he’s bringing musicians in from nearly everywhere to perform and to mark the publication of the book. The event is sold out but he’ll be streaming it. Watch it here.Let’s talk with David Monette.
