Gnarls Barkley Polishing New Album

In an effort to have the most appropriately titled album of the year, eclectic alt-rap duo Gnarls Barkley has dubbed their sophomore effort , 'The Odd Couple.'

The duo -- which consists of musical auteur Danger Mouse and oddball rapper/singer Cee-Lo -- is still in the lab working on new material for the follow-up to their 2006 debut, 'St. Elsewhere,' and have reportedly laid down tracks in Atlanta and Los Angeles.

While the duo continues to polish 'The Odd Couple,' a new track entitled 'Run' is making its rounds on multiple file-sharing sites. According to GnarlsBarkley.com, 'The Odd Couple' will hit stores in April.
