Reviewed with 4 stars (Excellent) in Downbeat, Invincible Nimbus is in the Hot Box of the June issue, with the following quotes:
"If you liked Dave Holland’s ebullient ’80s quartet, you’ll love this album by Danish bassist Anne Mette Iversen’s Ternion Quartet. Though not derivative, Ternion’s inside-outside free-bop recalls Holland’s playfulness, swinging momen- tum, fondness for unusual meters and delight- fully exposed horn lines, unanchored by a chord- al instrument." - Paul de Barros
"Melodically complex, Iversen’s deliberately scattered musical lines evoke bright, expressionistic images and inspire sophisticated improvisations from the Ternion Quartet; with Iverson at the helm, each player telegraphs confidence and daring as a soloist. The excitement lies in the ever-shifting mix of musical ideas that this skilled group generates." —Suzanne Lorge
"Hard swinging, full-on buoyancy, deep intersections, fluid curves, unabashed zest–OK, you get the point. The bassist’s foursome sounds bigger than it is because it’s always reaching out for more music to grab." —Jim Macnie
"Cerebral enough to keep your ears perked, swinging enough to keep your feet tapping while consistently boasting humor and wit; the music bewitches on multiple levels." —John Murph
