Jazz aficionados and genre stretching extraordinaires Medeski Martin and Wood return in style with another mind-bending masterpiece. This installment is titled Uninvisible.

Continuing from the groove-laden textures of 2000’s The Dropper, Uninvisible is another widely eclectic creation from the ever-gifted trio of MMW. Uninvisible sheds genre classification like unneeded skin while dabbling with acid jazz, sampling, voice-overs, hip-hop and anything else that helps propel a groove.

While primarily a groove-based record, Uninvisible still manages to cover a good bit of geography while harnessing its flow. Taking cues from Miles Davis’ early ’70s fusion work, Uninvisible seamlessly pulls in rock and funk into its jazzy base.

The title track, “Uninvisible” highlights former child prodigy John Medeski’s signature B-3 organ and includes a bass-line that is funkier than a James Brown look-alike contest.

The heavy beats and dissonant horns of “Nocturnal Transmission” are highly reminiscent of fellow avant-garde jazz contemporaries Isotope 217, an offshoot of Thrill Jockey records heroes Tortoise, who also sound like they influenced the band on tracks like the tribal “Retirement Song.”

At certain points, Uninvisible takes a path toward the spooky. Almost Doors-like in its eeriness, “Your Name Is Snake Anthony” is an odd excursion into psychic territory, adding a strange voice-over narration about living on the road with the creepy Snake Anthony.

In what could be a B-movie soundtrack piece, “Off the Table” is spine-twitching fun, complete with mimicked horror movie screams and other dastardly atmospheric treats.

Aptly titled, “The Edge of Night” sounds like a spacey requiem for some sinister alien.

While juggling intricate and often circuitous grooves, MMW never seems to ride the same pony for too long, keeping most jams around the four-minute mark. Not surprisingly, most of the fourteen tracks began as single-take improvisational jams then given further depth by samples or the addition of voice accompaniment.

The eagerness with which MMW embraces experimentation has given them the reputation for being such an innovative and influential trio. Uninvisible proves the band seems never to tire nor are they eager to repeat past triumphs. They are constantly reinventing themselves, while somehow staying eternally fresh.

What seems most evident is the unparalleled musicianship of MMW and their desire to make complex and challenging music that can still make you shake your respective booty at any given turn.
