I've known Jay Alan Yim since my time as a graduate student at Northwestern University. I had a fantastic time in his "Music Since 1975" class, including sprawling conversations about aesthetic issues that somehow wound up talking about initially unrelated issues and being forced to engage with music I thought (and continue to think, in some cases) that I hated.
Jay is a composer of incredible intellect and wide-ranging interests. His scores can range from the carefully constructed and sculptural "Blue Voice of Air" (that you can check out below) to this spacious multi-layered structure with elements of improvisation I was a part of performing back in 2009.
I always imagine a bold, geometrically bristling modern sculpture when I hear this piece. Also, fish making music...c'mon!
