Haven't heard Harnocourt's Haydn symphonies. I have a few done by Frans Bruggen and a period instrument group on Phillips. Very good. Pinnock recorded six CDs of the symphonies. I think the set is called Haydn's Sturm and Drang symphonies. I can' find it listed at Tower, Amazon, or Arkivmusic, so it's probably not being imported into the states by DG. However you can get it at mdt. a mail order store in Britain. This is a great outfit, btw. Often you can get European titles cheaper there than you can in the states even in these days of the weak dollar. link

Tyson, the Pinnock performances of these symphonies are just as you expected - excellent. Maybe a little bit livelier than Goodman, but I like Goodman nearly as well. When I got these recordings when they were first released, they sounded very harsh and forward, but that was alleviated as I upgraded my equipment. They now sound great.
BTW, nearly all of Pinnock's DG recordings are now being rereleased at a reduced price which makes them great bargains. Handel Concerti Grosso, Organ Concertos, Corelli Concerti Grosso, Handel's Water Music, etc. all tops.
