Diamond Eyes is the sixth studio album by American alternative metal band Deftones, released on May 4, 2010 by Reprise Records. It was the first album to feature bassist Sergio Vega, who replaced original bassist Chi Cheng. An album tentatively titled Eros was originally intended to be the band's sixth full-length release following Saturday Night Wrist (2006), but was not released due to Cheng entering a coma after a serious car accident that occurred in November 2008, eventually resulting in his death in 2013. The band continued on with Vega as his replacement, and the release of Eros was put on hold in favor of Diamond Eyes in June 2009.
