Michael Bublé on Inspiration for New Album, 'Nobody But Me'

— -- Michael Bublé said he learned an important lesson when making his new album, “Nobody But Me.”

“You leave your comfort zone, you grow,” Bublé, 41, said today on “Good Morning America.”

“Nobody But Me” features classic songs reimagined by Bublé. The album is the first that Bublé has produced himself.

“Everyone in my life thought I was crazy, that I was throwing it away, that I was making the decision that was the worst decision you can make,” he said.

But, he said, “It was so fulfilling to be with my best friends and create something.”

Bublé drew upon songs from what's called The Great American Songbook, the canon of the most influential American songs from the early 20th century that Bublé called “the greatest gift America ever gave to the arts.”

“I love the fact that I get to continue the legacy of my idols,” he said. “My job is to make it more authentic than it’s ever been before.”

Bublé said he chose the songs on “Nobody But Me” with “great difficulty” because they are tunes he may have to sing for the rest of his life.

He also described the intimate way he recorded many of the songs, including “God Only Knows” by Brian Wilson.

“I went in the studio, shut off all the lights, put my piano next to my mic and shut the lights completely off and put a picture of my two kids and sang the song to them,” said Bublé, the father of two young sons. “When you hear the record, you get a sense of that intimacy.”

"Nobody But Me" is available now.
