Next month Chicago cornetist Rob Mazurek debuts two new related projects. On March 21 his trio Throne of the House of Good and Evil, with drummer John Herndon and bassist Matthew Lux, plays at the Hideout, and a few days later his Pulsar Quartet—the same lineup plus superb New York pianist Angelica Sanchez—debuts with a four-night residency at the Whistler. But one of Mazurek’s most durable units has also been busy: in two weeks the Chicago Underground Duo, his project with percussionist Chad Taylor, releases Age of Energy (Northern Spy), its first new album since 2010’s Boca Negra.
