The standout track, “Amor,” is a simple tune with a catchy backbeat and lyrics that cease to complicate concepts of love.

What had been the backbeat of a bygone epoch, the waltz amazingly survived in the 20th century.

It’s a jauntily asymmetrical tune that rides a bluesy riff and a backbeat from the drummer Dave King of the Bad Plus.

He brought an ensemble to the elegant Appel Room theater, overlaying syncopated backbeats, heralding horn lines and tapestries of Rhodes and distorted guitar.

“Deep Blue” touches on Minimalism, psychedelia and traditional jazz, with a steady backbeat, a polytonal piano lick, electric sitar and back-talk from trumpet, clarinet and violin.
