New York: Pop celebrity Justin Bieber says he is developing a "futuristic" sound for "very personal" songs as he completes a long-awaited album.
The 21-year-old Canadian singer revealed that he is performing both drums and guitar on the album, on which he is collaborating with electronic producer Skrillex, legendary rap and rock producer Rick Rubin, and rap giant Kanye West.
"I`m at a place where I`m really happy and I`m ready to share my music," he told lifestyle mogul Martha Stewart in Interview magazine.
"Skrillex is on a really new wave and has found a way to take my vocals and mix them and play with them and pitch it up to make it higher with these cool effects that sound really futuristic," he said.
Bieber -- who has been known as much for his colorful life as his music since his last album "Believe" came out in 2012 -- said that the album will be about "stuff that I`ve been through."
"It`s just very personal. People will be able to really get into where my heart is," he said.
Bieber, however, did not offer a timeline for the album`s release.
"I`m really not worried about when it`s finished, I just want it to be perfect, so we`re taking our time with it," he said.
Bieber also told Stewart, who has developed a friendship with the young singer, that he is single.
When Stewart told him that "after this interview, every girl in America will want you," he replied unabashedly: "I think so, too. I`m a pretty lucky guy."
