Deftones have released "Smile" from their unreleased album, Eros, which was the last material to include bassist Chi Cheng, who passed away one year ago to the day. The album was shelved as the band's main focus became Cheng's condition after his car accident in 2008. They later made the decision to move forward with bassist Sergio Vega and would go on to release 2010's Diamond Eyes instead. No official release plans have been announced for Eros.
