As part of the three-headed songwriting monster of the Drive-by Truckers, Jason Isbell was overshadowed by Patterson Hood's grim, vivid, and vernacular Southern tales sung with an inimitable, scorched voice that could become a haunting howl.

That says more about Hood than Isbell, though. Isbell wrote some the Truckers' prettiest music, but the band has never been much about pretty. Its three-guitar attack and working-class outrage meant that Isbell's songwriting and singing contributions to Decoration Day, The Dirty South, and A Blessing & a Curse got largely lost. And the truth is that his vocals are probably better suited to the Eagles than the Truckers.

When Isbell in 2007 split from the band (by all accounts amicably), it freed his songs from the Southern-rock context and gave them the space to be appreciated on their own. And following a 2007 solo debut mostly recorded with his Drive-by Truckers bandmates, the new Jason Isbell & the 400 Unit - released in February - represents a clean break.

Most folks don't like to talk about painful personal stuff, such as a failed relationship.

William Fitzsimmons -- who will be performing a Daytrotter show on Thursday, March 19, at RIBCO -- doesn't have much choice.

"I wrote a record on divorce, so I opened the door," he said in an interview this week.

You'd never guess that The Sparrow & the Crow, Fitzsimmons' album from last year that the Boston Herald called a "near masterpiece," is about divorce on first blush. It's unfailingly delicate, intimate, and gentle musically, with folk-y lead piano and acoustic guitar lightly accented with other instruments. And it starts with the words "I still love you" and "I still need you" and what sounds like a reaffirmation of marriage vows. It absolutely does not sound like divorce.

If you want a sense of how excited the music press is about the up-and-coming South African psychedelic rock band Blk Jks (pronounced "Black Jacks"), you only need to see the art-rock royalty that reviewers name-check.

The stuffy New York Times: "Far closer to TV on the Radio and the Mars Volta than they are to Ladysmith Black Mambazo."

The hipsters at Spin, dubbing Blk Jks a "hot new band" earlier this month: "The electro-funk experimentalism of TV on the Radio with the Afro-pop guitars of Vampire Weekend, and drop in hints of jazz, ethnic African music, and the prog-rock of contemporary acts like the Mars Volta."

If those descriptions pique your interest, Daytrotter.com is bringing Blk Jks to the Quad Cities, and fans of adventurous rock would be foolish to miss the band's performance at RIBCO on Tuesday, March 3. This is a buzz band poised to make seriously good noise.

The influences of the Brooklyn-based duo KaiserCartel include punk rock on the "his" side and The Cure and My Bloody Valentine on the "her" side.

But good luck finding much evidence in the sound of the group, which is playing at RIBCO on Thursday in a Daytrotter.com show. The band's music is largely acoustic pop, and Courtney Kaiser's voice has a character like Aimee Mann's but without the flat disillusionment. Whistles and xylophones add sunshine to some tracks, but there's also a magnetic sadness in many.

Kaiser and Benjamin Cartel - both of whom sing and play multiple instruments - insist that the influences can be heard, and their comments reflect a wise understanding of the efficiency and directness of their own songs.
