Deep. So very, very, deep. Rarely does a single four-letter word so eloquently and accurately capture the spirit of an album. Everything from the grooves to the compositions to the thought content embedded in each musician's statements can be summed up by that simple-yet-complex title.

The Moutin brothers—bassist Francois and drummer Louis—formed the Moutin Factory Quintet back in 2013, expanding on their already established musical ties while giving further credence to the notion that twins share a special bond and language. The band's debut—Lucky People (Plus Loin, 2013)—was engaging, full of strong work and showing great potential; Deep is that potential fulfilled. Everything is in its right place here. Sparks fly and instruments alternately sting and sigh, as swift action figures into this exquisitely-shaped work of thinking men without ever overextending its influence.

The pieces that tend to carry the day in this set are not the most driven. Instead, it's "Love Stream," "A Soothing Thrill," and "In The Name Of Love"—songs that play light against darkness, creating audible shadow worlds in the process—that remain fixed in the brain. Playful presentations like "Fat's Medley," driven numbers like "Shift," and toothier offerings like "Exploded View," "Hell's Kitchen," and "Bliss" provide welcome thrills—
