Creativity and Its Sources / Tom McCarthy’s Remainder
Reading Tom McCarthy’s novel Remainder, which I love, I’m reminded of a realization I had a while ago: pure creativity is closely related to dreams — a mysterious place where new visions are somehow born. You dream, and you see … Continue reading

Short songs with absurdly long codas
Form-wise, the Beatles’ Hey Jude is unusual. For 3 minutes and 8 seconds, it’s a conventional song, with melody, varying harmony, A and B sections that repeat in a predictable pattern — what you’d expect from a pop song. Then, for … Continue reading
The TRAPPIST-1 System: Listening to Planetary Orbits
(Cross-posted from WBGO.org. Thanks to Nate Chinen for inviting me to write this.) With most things, I’ve found, what’s most interesting isn’t the thing in itself, but rather how it relates to other things. In other words, everything is relative, … Continue reading

Lee Konitz on Spontaneity, Originality, Drugs & Playing Sharp
Lee Konitz will be turning 87 in October, and his long and distinguished career as one of the most singular saxophonists in jazz needs no introduction (but if you need one, it’s here). He is known in particular for his … Continue reading

The composer Anna Clyne and I got together yesterday evening to catch up, and since we were at my place, and there were microphones lying around, we decided to make a track. I met Anna at the University of Edinburgh … Continue reading
It’s also about the notes
I dropped by 5th Estate in Brooklyn tonight to play some sax at the jam session, and had a conversation there that brought up a nice memory: it was shortly after I started playing with Lee Konitz, in early 2007. … Continue reading
Paul Motian, 1931 – 2011
I have a really clear memory of dropping in on a trio set with Paul Bley, Gary Peacock and Paul Motian while passing through New York when I was 17 or so. It was Motian who struck me the most: … Continue reading
