This is easily one of conductor Nickolas Harnoncourt's greatest recordings, the 1990s collection of Haydn's horn-driven symphonies Nos. 31 "Hornsignal," 59 "Fire" and 73 "La Chasse" or the chase. The braying of four natural horns that opens Symphony 31 is the best sound this music has ever had going for it!
Traditionalists that don't like period strings and sound are probably the only people that shouldn't bother with this issue. Harnoncourt is one of the crown princes of the period movement, perhaps establishing the first well-known period performance way back in the 1960s with that recording of Bach's Brandenburg Concertos. His band uses period instruments and plays without vibrato here but that hardly does anything to get in the way of these magnificent renderings.
Everyone else is going to be swept away by the elan and joie de vive of the Hornsignal, masculine playing in the Fire symphony, and the dance rhythm the conductor gets out of his orchestra in the chase. For his part, Harnoncourt is on his best behavior, eschewing the many highly personal and idioscyncratic devices he often injects into music of the great composers. No great slowdowns, stop or ritards affects this issue.
If you haven't yet made the adjustment to period performance, some of the vigor here can be had in this hybrid super audio recording from Jaap van Zweeden, who scowl on the cover belies the fun and friendliness Haydn put into this music.
