The Nextet is a snap perfect jazz rock fusion unit, actually a sextet, with electric guitar and bass, sax, drums, trumpet, and Aronow on electric piano. The sounds come straight out of the ’70s, the height of fusion, but with Latin and R & B flavors, and the music is completely contemporary and fresh.

There are geometric patterns to the band’s interplay, like shifting circles that break and turn into squares and stars and rectangles, laid one on another in a shimmering architecture.

“Ode to the Bicycle” is a title that says it all, the physical, fun exhilaration, the rhythm of the pedals as they ride into a mellow breeze. Aronow raps the lyrics, and it’s funky, with sax punctuations evoking Maceo Parker. The guitarist outlines the tune with octave intervals, and the trumpet puts on the brakes to end the song, like someone pushing the horn on a car.

The next number is soft Latin, with sax dropped for flute. We see why it’s called “Nextet” now. We’re always on the edge of our seats, elbows on the table, anticipating what comes next.

Aronow’s keyboard style is understated. He favors lower and upper ranges, a gentle charm, simple, subtle syncopation, warm, sticky melodies. This is a band of cohesion and flare. It feels good, it’s complex, but you always get what’s going on with an easy ear, open to the mutating patterns and effervescent color changes.
