The singer-songwriter remains influential in jazz, but improvisers have yet to fully mine his repertoire. Here are a few of the attempts so far, from musicians such as Kenny Garrett, Carmen Lundy and George Benson.

Professing love for Bob James' music can yield a side-eye in some circles, as his 1970s work is seen as a progenitor to smooth jazz. But he certainly knew his way around a catchy melody and an infectious riff — as legions of rap and house producers have discovered through sampling.

In the 1980s, pianist Michele Rosewoman and drummer Francisco Mora-Catlett started independently pursuing a mixture of Afro-Caribbean mysticism and avant-garde jazz. Thirty years later, they've finally recorded their otherworldly large ensembles.

For saxophonist Dayna Stephens, serenity has been a key to dealing with a rare kidney disease. It's filtered into his playing and composing, which is on the upswing despite health challenges that drain hours from his days and thousands of dollars a week from his limited budget.

In Sonnymoon's "Just Before Dawn," Anna Wise's ethereal vocals float across a palpitating soundscape. "Every night, you should have someone to hold," Wise sings, "to tell you that you did okay when your mind is against you."

When "Elephant Rose" concludes, it reveals Tixier as not only a remarkable improviser, but also a cunning contemporary jazz composer. He knows full well how to hint at a yesteryear classic, tap into modern-day nostalgia and still bring about something fresh and clean.

Underneath the firepower in Rodriguez's enchanting "Fog" lies the work of a remarkable composer.

"Welcome Earth Song" conjures the spirit of Sanders — as well as a soul-stirring church service.

Drummer Johnathan Blake tackles Robert Glasper's "Canvas," and in the process gives it a renewed sheen.

The jazz singer tackles Bush's classic "Love and Anger" with a sharp mind and a soulful heart.
