Also on the program, and not insignificant, was Haydn’s Symphony No. 103, the “Drumroll,” one of the most adventurous and brilliantly scored of the 12 “London” Symphonies. We haven’t heard enough Haydn from Salonen lately; it makes for a superb matchup. Something about the edge in Haydn’s humor — the way, in this work, that the finale builds its theme on the repeating figure in the horns, and the back-and-forth major-minor in the slow-movement variations — exactly works in Salonen’s hands, and always has. No. 14 was a valuable experience, I suppose, but it was the Haydn that rode home with me in my head, and remains today.
