Just three days after announcing a new strategic alliance with EDM powerhouse Ultra Records, news is emerging that Columbia Records has signed Daft Punk. A source confirmed that it's a "done deal." The revered, reclusive and highly influential French DJ duo had released all previous recordings via EMI's Virgin Records, now owned by ...Universal, with the exception of its most recent full-length, Disney’s Tron: Legacy, which Daft Punk’s Guy-Manuel de Homem-Christo and Thomas Bangalter scored. Prior to Tron, the last proper Daft Punk album was 2005’s "Human After All." Signing the electronic music pioneers is a major coup for the venerable 125-year-old Columbia, which also recently added Depeche Mode to its roster. Confirmed details about Daft Punk’s forthcoming fourth album are few and far between, although producer/Chic co-founder Nile Rodgers recently hinted that it would be out in the coming months. Singer/songwriter/ASCAP president Paul Williams, veteran bassist Nathan East, Feist collaborator Chilly Gonzales and legendary disco producer Giorgio Moroder (via a spoken monologue) are among others who have reportedly collaborated with the duo over the past couple of years, although whether and what form their contributions to the album might take is unclear.
