Evgeny Pobozhiy, a virtuoso guitarist with a busy profile on the Moscow jazz scene, has won the Herbie Hancock Institute of Jazz International Guitar Competition. As winner of the prize, one of the most prestigious of its kind, he'll receive $30,000 in scholarship funds and a recording contract with the Concord Music Group.

He also joins an honor roll of past winners including pianist Jacky Terrasson, saxophonists Joshua Redman and Melissa Aldana, and singers Jazzmeia Horn and Cécile McLorin Salvant.

"There is never any end," John Coltrane said sometime in the mid-1960s, at the height of his powers. "There are always new sounds to imagine; new feelings to get at." Coltrane, one of jazz's most revered saxophonists, was speaking to Nat Hentoff about an eternal quest — a compulsion to reach toward the next horizon, and the next.

A wave of shock and sadness moved through the jazz community on Sunday, with news of the death of Lawrence Lo Leathers, a drummer with a steadfast presence in the modern jazz mainstream.

Leathers was 37. He was killed on Sunday in the hallway of an apartment building on East 141st Street in the Bronx neighborhood of Mott Haven, according to Detective Martin Brown of the NYPD. The police have arrested a suspect in connection to the incident.

There comes a moment in almost any performance by vibraphonist Joel Ross when he seems to slip free of standard cognitive functions and into a bodacious flow state. Invariably, he's in the midst of a heated improvisation. Maybe he's bouncing on his heels, or bobbing like a marionette. His mallets form a blur, in contrast to the clarity of the notes they produce. The deft precision of his hammering inspires a visual comparison to some tournament-level version of Whac-A-Mole.

Herbie Hancock took a moment during the International Jazz Day All-Star Global Concert to address some fraught geopolitical realities.

Not that Hancock, in his dual capacity as UNESCO goodwill ambassador and chairman of the Herbie Hancock Institute of Jazz, got into specifics, or really needed to. Speaking from a podium at Hamer Hall in Melbourne, Australia on Tuesday night, he just extolled the spirit of cooperation and exchange in jazz, "at a time when internal and external relationships among so many countries are unsettled."

Herbie Hancock and Kamasi Washington, two of the biggest names in jazz, will join forces for a North American co-headlining tour this summer.
