Recently, I've been thinking about performance practice and public attitudes toward "art music" more generally. A couple of specific things have influenced me, that I'll talk more about, but I wanted to mention them quickly. One is Emily Howell, a computer program developed by UCSC professor David Cope. (JFGI and read all about it).
The other is improvisation, especially by Gabriela Montero, of whom I was just made aware three days ago, and have not stopped watching obsessively since. My favorites here and here. I've never seen anything like it. The most shocking part for me is that I had never heard of her before! This kind of thing just isn't really encouraged much in the conservatory world that I inhabit, which is a real shame.
More generally, though my friend and I have our disagreements about what music is all about, I think we agree that something is off about the modern concert hall experience. More to follow soon!
