For what it's worth, I have enjoyed some of her discs. The ones I have
are modern though: Hindemith, The Four Temperaments and Strauss, Burleske.
In each case a first listen caught my fancy and made me want to listen
repeatedly, but I can't say how she might come across in Haydn. Also,
since the repertoire I heard is fairly unusual I can't really compare it
to other performers.
