It's not often you'll hear a story about label interference making a record better, so let's marvel at Hey Rosetta!'s Second Sight.

The band was twice short-listed for the Polaris Music Prize and has been nominated for a Juno Award - the Canadian equivalent of the a Grammy - and Second Sight has been warmly received. SputnikMusic.com described it as "a collection of profoundly beautiful and well-arranged songs that I'm sure will stand the test of time."

Yet the story of its creation shows some of the opportunity inherent in a little adversity.

The Canadian septet had finished recording the album's 11 songs, and the band's label liked it, but ... the staff felt it needed a single, something to launch it. Singer/guitarist/pianist/songwriter Tim Baker - in a recent phone interview promoting the band's April 24 Communion Tour gig at Rozz-Tox - said he disagreed.

"We thought we had a great record, and we had to go back in" to the studio, he said of the band's frustration. Hey Rosetta! assented because they also wanted to make the album as commercially viable as possible, "to get it out to people."

But writing to grab people's attention is difficult, and something that was foreign to Baker as a songwriter. "I'd never written a single before," he said. "We'd gotten this far just playing our sprawling tunes and touring all the time. If we were going to try to get something on the radio, then I really wanted it to be moving and really mean something to me. And hopefully be one of those songs that isn't just skin-deep, kind of asinine music. ... A song that actually reaches past and does something to you. ...

"We took it as a challenge ... trying to write something short and catchy but meaningful. ... I think we got it, but it was a trial for sure."

I'm trying to pin Chris Noth down on some dates, and he's not helping.

"The older you get," he said, "the years just start running together."

In fairness, it's not merely age. The topic of our interview is Natty Scratch, the band Noth co-founded that will be celebrating 43 years of existence this weekend with a pair of shows featuring all the group's original members - and people who've joined over the years.

The band's current lineup includes founding members Noth (guitar and vocals), Tommy Langford (bass and vocals), and Steve Cooley (percussion and vocals). Keyboardist Rick Stoneking joined in the early 1980s to replace Noth (who joined several touring bands), and drummer/vocalist Richie Reeves has only been with Natty Scratch for about a decade.

For this weekend's concerts, the group will also feature original drummer D.L. Blackman (who cut back on performing, making way for Reeves) and - returning from Alaska - guitarist/singer/co-founder Pat Ryan. (Noth said he's not sure when Ryan left the Quad Cities, except that it was before his own return in 1991.)

Culture Coup, Blue Faith Sunrise

Music rooted in reggae has an inherent warmth, and that's certainly true with the Quad Cities quintet Culture Coup on its debut album, Blue Faith Sunrise. But it doesn't take much time with the record to notice that there's a drag on that vibe, an early-adult ennui in the vocals and lyrics.

Rather than being a wet blanket, however, that contradiction actually enlivens the 11-track whole - bringing a welcome complexity to a style that too often feels one-dimensional to me.

Lead singer/guitarist Ben Miller, guitarist/singer Chris Miller, drummer Jack McNeil, bassist Jim Drain, and keyboardist/singer Joey Pautsch successfully meld the building blocks of reggae with indie-rock's youthful angst, and crucially they never coast on easy grooves. Every song features some combination of compositional depth and articulate playing, particularly in the drums and lead guitar. There's often a magical interplay among the instruments, a cohesive collection of distinctive voices.

All Them Witches hails from Nashville, and the combination of name and hometown gives you a pretty good sense of a split personality. The moniker hints at a band in thrall to Black Sabbath, and the Tennessee city hints at something Southern - although its debts are to blues and Southern rock and not in any way country. (Bassist/singer Michael Parks Jr. noted, however: "We have been known to just pop up on the street somewhere during tour playing bluegrass on the street.")

But when the band returns to Rozz-Tox on February 15, it will be apparent that the quartet is far more expansive than that would suggest. All Them Witches embraces not just blues-based music but the blues themselves, particularly on "The Marriage of Coyote Woman" from its most recent album, Lightning at the Door. The elemental riffs of Ben McLeod have the heaviness of Sabbath's Tommy Iommi but also the razor-sharp lyricism of Queens of the Stone Age's Joshua Homme.

And, most importantly, there's an experimental psychedelic core, a grounding in improvisation that allows each person in the band to bring a distinct personality to tracks that might go anywhere - including, to cite just one example, throat singing in the folk-ish and completely un-metal "Romany Dagger."

And that anything-goes quality is the reason I was curious about this comment I read from drummer Robby Staebler: "As individual players we are more concerned and focused on our own playing. We are not focused on what the others are playing. We all do what we want. It's why it works."
