I've been listening to the wonderful music produced by the 'Standards' trio first formed by Keith Jarrett back in 1983. Their latest - The Out Of Towners - is as good as anything that Jarrett and his partners, Gary Peacock and Jack Dejohnette, have produced in that time. Unlike some work in the trio format, there is a palpable sense of conversational give-and-take in the heat of creativity and the release of joy in the improvisation. There's little doubt that we are living through a new golden age of the jazz trio with artists like Brad Mehldau and Ahmad Jamal mining a rich repertoire. But Jarrett-Peacock-Dejohnette are still setting the standards.
