The new Gnarls Barkley album will be called "The Odd Couple", the pop pair have confirmed.
The follow-up to 2006's "St Elsewhere", which included the record-breaking UK Number One "Crazy", is currently nearing completion.
Producer Danger Mouse and singer Cee-Lo are reported to have finished the album recently in Los Angeles, reports Billboard.
Unlike their debut, which was built upon a foundation of samples and electronics, the new recordings will apparently feature live instruments.
"The Odd Couple" is due for release in April.
