It all amounts to a top-to-bottom renovation of one of the most stable operations in the music business, with a mostly older, mostly female fan base (Oprah Winfrey is a big fan) and more than 20 million albums sold.
“I really left behind every safety blanket I had,” he said. “I had just come off the heels of the No. 1 record of the year, and I can’t count how many times somebody came up to me and said, ‘Oh, are you going to make another Christmas record?’ You think to yourself just how easy that would be to keep recording Groban does this, Groban does that.” And there might be a time in his life, he added, where he would “feel perfectly comfortable” with that. “But for better or for worse, there’s still some fire and some exploration in me. I felt like it was a natural progression for me to start making it a little more personal.”
Intimacy and grandeur are hardly opposites in the world of Mr. Groban, 29, who was once memorably pegged (by Stephen Holden in The New York Times) as “our national choirboy.” But many of the songs on his previous albums offer the equivalent of a love note etched in skywriting, suitable for ceremonial purposes. “Illuminations,” which showcases Mr. Groban’s songwriting, reflects the conviction that gallantry can also be pensive and uncertain.
On the surface Mr. Rubin, best known for his work with the Beastie Boys, Metallica and late-period Johnny Cash, would seem an unlikely fit. But Mr. Groban was a fan. “You don’t hear a stamp so much, like you do with other producers,” he said of albums produced by Mr. Rubin. “You hear the most honest, organic representation of that particular genre and artist.”
The admiration was mutual. For Mr. Rubin the collaboration posed a challenge: “My goal was to make an album that was different than all the albums he made before and that would be the favorite album of people who love him. I also wanted it to be the album that people who didn’t like him would like.”
When it comes to his wholesome image, Mr. Groban is definitely in on the joke. An avid karaokegoer and a deft mimic, he has put in cheeky cameos on “Glee,” a series that embraces what he fondly calls “big singing.” In a video recently posted to the Web site Funny or Die he plays his own hapless interviewer. (“My mom’s a big fan, by the way.”) And in “Crazy, Stupid, Love,” a coming movie starring Emma Stone and Steve Carell, he plays a caddish lawyer — the humor arising partly from the sheer implausibility of such a thing.
Behind the self-deprecation, though, is someone acutely aware of outside perceptions. “All of a sudden when success hit, you get demos from publishing companies, and you wind up saying: ‘Is this how they view me? Is this what they think I am?’ And you realize: ‘Well, yeah, if you don’t do anything about it, you’re just going to get a bunch of songs like this.’ ” The urge to write, he said, “started with hearing things I didn’t want to sing.”
