Hi! Actually the trip that I'm planning is pretty far from both locations.. I'd flight to Denver and from there I'd like to do a loop and visit Colorado,Wyoming, Utah. But I've check I could add a intermediate stop with almost no extra cost before or after the trip (I could do Italy-Boston-Denver-Italy or Italy-Denver-LA-Italy). Only, going to Tanglewood takes some more time because there is a 3.5 hours bus trip from Boston. And besides I should arrive the day before the concert. But a JW concert definitely worth it! Anyway, I've just bought for 70$ the last ticket available for the first block of rows for the Tanglewood concert . In the left corner, very close to the the stage. I'm still not sure to be able to attend, but I have the ticket, just to be safe
