It would have been easy for Linkin Park to coast along, cranking out more of the catchy, hip-hop-textured rock that had long been its stock-in-trade.
The California six-piece was, after all, the best-selling new band of the '00s, scanning more than 21 million albums in the United States and becoming a fixture at hit radio with songs such as "What I've Done" and "In the End."
But for band leaders Mike Shinoda (rap vocals, guitar) and Chester Bennington (vocals), kicking back wasn't a very enticing choice. So last year they steered Linkin Park into ambitious new territory with "A Thousand Suns," an experimental, high-concept fourth album that has kept fan debates roiling for months.
"As the years go on, we're learning new things," Shinoda told journalists in a teleconference ahead of the band's Tuesday visit to Joe Louis Arena. "We're changing. We're listening to different music. We're playing different instruments, interested in talking about different things. So all of that stuff gets mixed into the pot and at the end of the day, the music is built upon all of that stuff."
The new direction was apparent from the earliest demo sessions for "A Thousand Suns," a sound Shinoda described as looser, more electronic, more abstract. The band tapped an age-old technique known as "automatic writing," adapting lyrics from a stream-of-consciousness flow. And with Rick Rubin -- who had also produced 2007's "Minutes to Midnight" -- the group found a receptive accomplice for its new sonic adventure.
The resulting album was a far cry from the Linkin Park of a decade ago, the band that turned out a monster debut in the form of "Hybrid Theory" -- all adolescent angst, roaring nu-metal guitars and crisply alternating rap-singing. The kaleidoscopic "A Thousand Suns" reveals a band in transition: Roles are morphing, sounds mutating. The lyrics have become political. Guitars have made way for pianos, synths and processed noise. The acoustic song "The Messenger" closes the album on a radically different note.
And while the catchy bits are intact -- Linkin Park probably couldn't stop the hooks from seeping out if it tried -- the band approached the album as an album, rather than a selection of tracks.
"We wanted to have a vibe," said Bennington. "We wanted the album to be presented as a piece of art, as a whole."
The sounds are cutting-edge, even futuristic. But the album's flow, said Shinoda, was intended to hark back to the concept records of the 1970s, cinematic in scope.
"The approach is to try and make it almost more visual, to really pace it in a way that paints a picture and is not about, like, hitting you with pop songs," he said.
In a music industry that is increasingly geared toward tracks and downloads, Shinoda, Bennington and their band mates -- guitarist Brad Delson, drummer Rob Bourdon, bassist David Farrell and DJ Joe Hahn -- knew they were taking a risk.
"We had to look at ourselves in the mirror and say, 'Are we comfortable with the possibility that this will work against us in the long term?' " Shinoda recalled. "Obviously we decided to go through with it and go against the grain. And I feel like creatively, artistically, it was a choice that we needed to make."
While "A Thousand Suns" prompted a mixed response among the Linkin Park audience, the more severe backlash seems to have dissipated with time as fans grow into the music. And the album's first two hits -- "The Catalyst" and "Waiting for the End" -- have probably lured more than enough new fans to compensate for any departures. Like each of Linkin Park's albums since 2003, "Suns" debuted at No. 1 in Billboard. Still, its first-week sales of 241,000 were significantly lower than the 625,000 for "Minutes to Midnight" three years earlier.
"The diehard fans of Linkin Park are really open-minded to what we do," said Bennington. "Sometimes it takes people a while to digest the new music. But when it sits -- especially with this album -- I think people really are going to appreciate what we've done here and see it for what we intended."
Shinoda, a gadget whiz and studio fiend, has always injected a high-tech feel into Linkin Park's studio work, one that must ultimately be translated onstage. But material from "A Thousand Suns" may prove even more challenging than usual. The band got a chance to start honing the music with a run of overseas dates in the fall, but the performance will continue getting tweaked and improvised as the U.S. tour gets under way tonight in Florida.
The group would like to eventually stage full front-to-back performances of the new record, Shinoda said, but he emphasized that the current tour will include music from the band's entire catalog.
"I think they work well together," he said. "The new record definitely lends ... a narrative to the show, which is really nice. It kind of ties different parts of the show together, and I find that some of the old songs take on a new meaning when they're put in that context."
