When I talked with Nathaniel Rateliff earlier this week, he was driving a dump truck for his job as a gardener, and closed the interview with these pronouncements when asked if there was anything he'd like to mention: "I love to swim. I like poultry."

Aside from hinting at a dry sense of humor, these things suggest that Rateliff is grounded person. And that's reflected in the path that he's chosen.

The Denver-based singer/songwriter, who will perform two Daytrotter.com shows on August 27, had an opportunity to have his rock band (Born in the Flood) and perhaps his current folk-ish outfit signed to the Roadrunner label. But he chose instead to follow his heart.

When Sean Ryan recorded his solo debut, Lonesome Driver Music, two years ago, his group the Dawn was around, but "I just wasn't ready to take the band I had into the studio," he said.

So he employed some noted local pros -- including drummer Marty Reyhons and guitarist Kerry Tucker, both from Einstein's Sister, and pedal-steel player Tom Pickett Jr. -- in the service of his songs, and the result was an excellent snapshot of a promising young writer and performer in good hands.

The Dawn has now finished its debut, and Ryan has clearly assembled a strong crew in the intervening period. Reyhons and Tucker still make contributions, but the self-titled record is anchored by a proper band: singer/songwriter/guitarist Ryan, Pickett, Jordan VanOpdorp on keyboards, Garrin Jost on bass, and Dave Soliz on drums. The band is an essential element, as Ryan's songs universally benefit from rigorous, full arrangements played with flair.

Chevelle's Sci-Fi Crimes raises one major question: Does the band believe in the paranormal subject matter it tackles with such earnestness on its 2009 record?

"Pete and Dean and I have this ongoing discussion about whether it can happen, whether aliens can even reach us," said drummer Sam Loeffler in a phone interview last week. "It's all in fun."

Which is to say that the members of Chevelle -- brothers Sam and Pete (guitars and vocals) Loeffler and brother-in-law Dean Bernardini (bass) -- aren't believers. Yet.

So when Chevelle headlines Saturday's Rock the District event in Rock Island, feel free to share your beliefs, theories, and evidence with the band. Sam, at least, claims to have an open mind.

Dan Snaith sounds tired of answering questions about math.

He comes from a family of mathematicians; he earned a Ph.D. in the field in 2005. And because he records and performs (under the name Caribou) electronic music, journalists (this one included) ask him a lot of questions about the relationship between his primary academic and musical pursuits. They both involve computers, don't they?

Snaith -- who will be playing with his band at a Daytrotter show at RIBCO on Saturday, June 5 -- said there are some similarities. But not many. "Being able to do what you want ... is kind of an intuitive process," he said in a phone interview last week. "In both mathematics and in music, you kind of have to use some gut-level intuition to piece things together. [But] I think they're very different in many ways."

What's evident listening to the music of Caribou is that Snaith's electronic instruments are largely tools, not ends. There are certainly electronic sounds, but the songs sound organic and feel handmade, and his singing voice is ethereal, warm, and emotive -- a perfect offset to any digital coolness. Put differently, there's nothing mathematical about Caribou's songs.
