As promised, the Deftones have entered the studio to begin work on their follow up to 2010's Diamond Eyes .

The band posted a photo of the mixing board, drums and mics along with the words "Day 1" via their Twitter. The album will again feature former Quicksand bassist Sergio Vega who joined the band after bassist Chi Cheng was left in a coma by a November 2008 car crash. While Chi has shown positive progress, he remains only semi-conscious.
