I have just listened to his violin sonata. By accident, the reason for which I got the CD with it was another piece by other composer. Anyway, I listened to it. It's very good piece. He had to posses great sense of writing for violin.
By the way, he died before his 24th birthday (January 20, 1870 – January 21, 1894).
And yet he has considerable oevure including orchestral music. I'm about to dig it soon. But chamber works first.
