Herbie Hancock, Ron Carter in Denver, Boulder on same night

Here’s something you don’t see every day in Colorado: two former members of trumpeter Miles Davis’ “Second Great Quintet” from the 1960s will appear, albeit on separate stages, in Denver and Boulder on the same night.

Keyboard innovator Herbie Hancock and bassist Ron Carter will perform in the area on Sept. 12: Hancock and his band at Boulder’s Chautauqua Auditorium, and Carter’s Golden Striker Trio at the new Dazzle location in the Denver Center for the Performing Arts. (Carter’s gig will extend to three evenings, through Sept. 14.)

Both are among the most accomplished artists of the last 60 years. Hancock has successfully performed in a dizzying array of styles, and has two platinum albums (sales of 1 million units or more), “Head Hunters” and “Future Shock,” to his credit. Carter, meanwhile, has appeared on more than 2,200 recordings in his astounding career, holding a Guinness World Record as the most recorded jazz bassist in history. Judging by the Carter-featured recordings I’ve heard over the course of my life, the quantity of his appearances does not obscure the quality.

If you’re fortunate enough to have a ticket to Hancock’s Boulder show, which is sold out (unless you decide to pay an inflated price through various ticket brokers), expect a wide variety of styles, from electronic funk to driving acoustic virtuosity. His current band includes trumpeter Terence Blanchard and guitarist Lionel Loueke, both brilliant leaders themselves. Carter’s trio should provide something more relaxing, as his group features the subtle guitarist Russell Malone and classically-trained pianist Donald Vega.
