Here’s a nice piece from the Chicago Sun Times on some of the young free jazz scene players in Chicago. Several of my Lucky 7s compadres get some nice props.
They swing, but they play free jazz. That is, they improvise freely (oh, no!), outside chord changes (shocking!), and sometimes they’re even arhythmic or atonal (the horror!). Sometimes their music is fierce, with exhilarated honks and explosions. More often, it’s intense, very tight group explorations, often lyrical or abstract or even charming.
