Editor's note: The Dirty Projectors show scheduled for Sunday, March 8, was canceled the day of the show.

Three years into its existence, the variety of acts that Daytrotter.com has brought to the Quad Cities for concerts defies pigeonholing, but they've tended to fall into two broad categories: the highly idiosyncratic and the on-the-verge. (Remember that founder Sean Moeller brought in Vampire Weekend, Blitzen Trapper, and Fleet Foxes before they were big.)

The closing track on Killin' It, the new release from the Quad Cities reggae-rock trio Rude Punch, is called "Payment," and unfortunately it's overdue. Loose and light, the guitars and drums at the outset seem to be searching for the groove, and when they find it 35 seconds in, they sustain it for another four minutes. Brady Jager's singing is heartfelt and nimble, and background vocals and twin guitars add satisfying accents and interplay, while bassist Robb Laake and drummer Adam Tucker are each given opportunities to fill in the gaps. The lead-guitar and drum breaks suggest a band adept at jamming within a song's structure.

I'm guessing the band's CD-release party on Saturday at the Redstone Room will be a good time, as its music goes down easily and has the benefit of familiarity. If you've heard reggae, you'll have plenty of reference points. Most importantly, the band works it right on stage, and "Payment" shows what they're capable of.

But the album itself suffers from a lack of imagination.

If you listen to the three bands on a Daytrotter.com bill at RIBCO next week, the impression their recordings leave might mislead you.

Headliner Deer Tick released War Elephant in 2007, and it's mostly a shit-kicker. But leader John McCauley said last week: "I'm certainly not a cowboy." And: "I was so sick of being called alt-country."

So he promises that Deer Tick's forthcoming album - due out this summer - will be more of a rock-and-roll affair. One can certainly imagine McCauley rockin' out, but it's hard to imagine him with less twang.

As Michael Doucet tells it, the Acadian people of Louisiana have in their blood a penchant for both adaptation and preservation. They moved from France in the 17th Century and colonized Acadia - in what are now the Canada Maritime provinces and Maine. And many settled in Louisiana after the Great Expulsion of 1755 and became Cajuns.

"I think our culture has always looked at this - and not necessarily intellectually, but more on an emotional level - that you would adapt to whatever was around," Doucet said last week in a phone interview from his southwestern-Louisiana home. "That's how the Acadian sort of ethnic culture continues to be vital today, because it adapted.

"That's what we're doing now, is adapting to where we are now."
