1849 - so it's an early 'Romantic' symphony.
Hubert studied with Mendelssohn from 1839 so he would have been aged 21+ and this symphony would have been composed during that time presumably.
I'd be interested to hear what influences you think are in evidence after listening. I don't hear much Mendelssohn to be honest which makes a refreshing change. I personally think he has quite an individual stamp

Thanks for that. I've sampled a few minutes and will give it a complete listen soon. Do you have details, re: orchestra, conductor, date ?
