After selling more than 22 million albums in the United States and becoming a staple in the classical music field, singer Josh Groban is embracing an edgier sound for his latest record, "All That Echoes," out on Tuesday.

Groban, 31, put together a collection of covers and original songs for the album, including a rendition of one of his personal favorites, "Falling Slowly" from the movie and stage musical "Once".

Under the guidance of veteran producer Rob Cavallo, the Warner Bros. Records chairman who has worked with rockers like Green Day, Goo Goo Dolls and Paramore, Groban showcases his usual smooth vocals against a more energetic, live-concert sound.

"It's not about walking out of your lane and scaring people. It's about slightly expanding what your lane is and allowing all of that to be part of your world," Groban said in an interview with Reuters.

Along with covers including a rendition of Stevie Wonder's "I Believe (When I Fall in Love It Will Be Forever)," Groban also wrote original songs, which he said emerged from frustration.

"It was the frustration of hearing songs that were maybe written for me after a little bit of success, going 'Ahh, is that really what you think I do?' Yes, I know the other thing was kind of cheesy, but that's really cheesy,'" the singer said.

"All That Echoes" features original songs such as "Below the Line," which draws in Latin jazz beats and sweeping ballads such as "Brave" and "False Alarms," where Groban showcases his powerful voice.
