Listening to some historical Sibelius recordings, mostly from the 1930s, with some pretty amazing transfers from 78s. Most of the symphonies are conducted by Robert Kajanus, who was Sibelius' favorite conductor. So, these were frequently either the first recordings of these works or close to it. So, it's fascinating to hear them and I must say I'm enjoying what I'm hearing - one does have to adjust one's ears, just as one had to for the Anthony Collins 50s mono recordings - those sound excellent but a bit limited in range and these from twenty years before sound pretty amazing for their age. But it's the performances here that's the thing.
