Right now, Dan Auerbach is living a rock-star moment, with his hard-hitting blues-rock duo The Black Keys selling out arenas all over the country. Lots of people want him on their records. So what does he do? He seeks out the 71-year-old Dr.

Critic Tom Moon reviews two contrasting perspectives on the intersection of jazz and gospel music. Multi-instrumentalist Don Byron has just released "Love, Peace and Soul" featuring his New Gospel Quintet. Also out is a set of duets between the late pianist Hank Jones and bassist Charlie Haden, titled "Come Sunday." Moon says the two projects reimagine old-time religious tunes in surprisingly different ways.

It's true that you can still get by in rock 'n' roll on the strength of a unique voice. But it helps if said voice has something interesting to work with.

On the first three records by Heartless Bastards, that wasn't always the case. The Mountain, from 2008, had some terrific songs about a breakup, and a few that got bogged down in a rut. But on the band's latest release, Arrow, every song has a powerful, almost magnetic melody.

Sometimes I wonder: Do the members of young indie-rock bands know that they're walking stereotypes? There's the scruffy dude who's obsessed with everything vintage and analog, the Pavement-worshiping, whiny-voiced lead singer, the rhythm section that knows its way around every oddity recorded by The Kinks. That's pretty much how I pegged the Philadelphia sextet Dr.

The hip-hop band The Roots might currently be the hardest-working band in show business. Five nights a week, it's the house band on Late Night with Jimmy Fallon, and is constantly collaborating with other artists. And this week, the band issued its 10th studio album.

Record producer Jonathan Wilson recorded his new album Gentle Spirit during little slivers of time when the artists he was working with — among them songwriter Jackson Browne and the rock band Dawes — were on break. The project took him four years to finish, and it's the musical equivalent of a landscape painting.
