Terry Teachout writes in honor of Mozart's 250th birthday. Excerpt:
[Mozart] was a child prodigy without formal education who wrote his first symphony at the age of nine and his last one a mere 23 years later, not long before his early death. All prodigies are by definition interesting, but in Mozart's case the interest is heightened by the fact that he not only died young but left behind an oeuvre so extensive and all-encompassing that it might as well have been the work of a fully mature composer who died at sixty, or even eighty.
The article includes a discography. Being acquainted with Teachout's excellent work, I suspect it's a selection we can trust fully.
