Adele is still peaking with 'Rolling in the Deep' and her '21' album, but she's already thinking about her next record, which she expects will be a more acoustic, stripped-down affair.

"It won't be a big production," the big-voiced singer says in a new interview. "I want it to be quite acoustic and piano-led. I want to write it, record it all, produce it all and master it on my own.

"I think it'll take a lot longer because I want to do it this way. When I move house in the summer, my sound engineer is going to come and help me install a studio and teach me how to use it."

It's cool to see such ambition from someone who could easily rest on her laurels if she wanted, given the massive worldwide success of '21.' As for when we can expect the follow-up, Adele says she's anxious to get started. "I've accumulated some things to write about again. I'd go into the studio tomorrow if I could."

'Rolling in the Deep' was just (finally) displaced from the No. 1 spot by Pitbull's 'Give Me Everything' after seven weeks at the top. Adele says she won't try to duplicate the success of her current album.

"I don't really care about expectations. There was enough of it with this record. If you deliver the songs I think you get away with it. I'm not bothered. I'm not expecting my next record to be as big as this one. That's impossible."
