Issued 15 years ago today, Björk’s ‘Medulla’ jettisoned every-day instruments in favor of the purest one: the human voice.

Rich Halley’s inspired collaboration provides the visionary interplay, the spirituality and, yes, the flair for melody that are hallmarks of both sides.

That feeling of not being able to fully grasp what’s unfolding is at the heart of the thrill of listening to ‘Radical Invisibility’ by Daniel Carter, Stelios Mihas, Irma Nejando and Federico Ughi.

Nothing was spared in making Wertico Cain and Gray’s seventh collaboration a rich listening and viewing experience.

The Michael Gregory Jackson Clarity Quartet’s ‘Whenufindituwillknow’ pulls together the guitarist’s many musical threads into a richly diverse basket of songs.

Jazz is the music of pure emotion, and it’s the vehicle by which Michael Bisio, Kirk Knuffke amd Fred Lonberg-Holm sorted out their feelings about a tragedy.

‘Echos la nuit,’ which translates into “echoes the night,” is a unique moment for Michaël Attias: This is his first unaccompanied album.

The enthusiasm that Jeff Cosgrove, Matthew Shipp and William Parker invest in pushing jazz into sweet freedom shines through on ‘Near Disaster.’

Performances like these are often called “spontaneous compositions” but in the case of Dave Rempis’ Kuzu, they’re often spontaneous combustions.

Matthew Shipp returns to his trio, using a common setup to make music that’s uncommonly advanced and stimulating.
