Few people would be surprised to find Julie Byrne working in the service industry. The singer/songwriter, after all, is in her mid-20s with one album to her credit, and it's hard for an emerging musician to make ends meet performing for small audiences and selling records one by one.

But if you see Byrne working at Rozz-Tox in the coming weeks, it's not for that reason. Instead, she's the first artist-in-residence at the venue, and her one-month stay in the Quad Cities - running through early June - will include a show on May 28.

The residency, Byrne said last week, originated with the idea of finding something to fill the gap between a two-month tour and her summer concert bookings. "I knew that going on such a long tour would be really wonderful and really exhilarating but also challenging just because there's no privacy and no space to reflect on these constant, rapid experiences - each day in a new place," she said. "So I was trying to figure out a calm, tranquil environment where I could exist after the tour to kind of take it all in and begin working on new material."

With the Water Liars's self-titled album - the band's third record in as many years - you could be forgiven for thinking that you're in for a jarring ride based on the song titles and the opening track's bleak but majestic riff. "Cannibal" is followed by "War Paint" and "I Want Blood."

You are in for a ride, although it's less the beat-down and carnage that the titles suggest than a careening from loud distortion to gentle Americana and back. "Ray Charles Dream" is a hooky, punk-tinged rock song sandwiched between the slow-footed guitar lament of "Tolling Bells" and the even-slower-footed piano lament of "Vespers."

"That's always been sort of a point for us," said singer/songwriter/guitarist Justin Kinkel-Schuster in a phone interview last week, promoting the trio's May 14 performance at Rozz-Tox. "Widely shifting dynamics has always been an important part of our sound ... both live and on records. ... I just always am intrigued by moving between those poles. There's something interesting about taking a ride like that."

It's not merely a sonic roller coaster. The title and sentiment of "I Want Blood" ("I want blood all the time") would seem to lend themselves to a ravenous rock treatment, but the song instead places the lyrics in a warm and ethereal musical context, making it a reverb-heavy anthem to searching and soaring. "Tension is why art exists," Kinkel-Schuster explained of the apparent contradiction. "Without tension, I don't think there's a whole lot to go on. ... Without tension you don't have a story; there's nothing to resolve."

Roughly a quarter-century ago, B.B. King said of Joe Bonamassa that "he hasn't even begun to scratch the surface."

It was an undeniable compliment to somebody not yet in his teens, but it was also a challenge - one that the blues-rock guitarist, singer, and songwriter apparently still takes to heart. Bonamassa continually scratches and scratches to get deeper.

His performance April 19 at the Adler Theatre will be one example, featuring a set with his acoustic band and another with his electric - both covering roughly 10 songs. The acoustic sets demonstrate that Bonamassa isn't content to skate by on instrumental virtuosity - unlike too many of his ace-guitarist peers. These shows require solid songs, nuance, and variety.

As he said in a phone interview last week, the two-set engagements are "very challenging vocally and on guitar, because you're essentially switching gears tune to tune."

Even better evidence of his range can be found in his recent discography. In the past two years alone, Bonamassa has put out the Driving Towards the Daylight studio album, live and studio releases with singer Beth Hart, the third and final album from the Black Country Communion super-group, a studio disc by the jazz-fusion Rock Candy Funk Party, Beacon Theatre: Live From New York, the live album An Acoustic Evening at the Vienna Opera House, and the four-disc Tour de Force: Live in London - documenting themed shows at four venues with different band lineups and more than 60 different songs. And he has a new studio album planned for fall release. (The old saw about the weather can be adapted for Bonamassa: If you don't like his latest record, just wait a few minutes.)

From an Adler Theatre stage filled with more than 200 musicians, the Quad City Symphony forcefully premiered Gustav Mahler's monumental Symphony No. 3 on April 5. Moving from the dissonance of uncertainty to the transcendental climatic moments of harmonic resolution, the concert was abundant in gravitas, contrasts, and drama that revealed a thorough artistic vision from Music Director and Conductor Mark Russell Smith and included a valuable collaborative process with other area musical organizations.
