Sergio Vega is an American musician. He is the bassist of post-hardcore band Quicksand, which originated in New York City in 1990. In 1995, Quicksand disbanded, although they reunited again in 1997 to tour with Deftones. After this tour, the band desired to write a follow-up to their last album Manic Compression, although tensions between bandmates caused the band to split up again, until June 2012 when another reunion was announced. Vega began playing for Deftones, replacing Chi Cheng after Cheng was involved in a car accident which caused him to enter a semi-conscious state in November 2008 and led to his eventual death on April 13, 2013. With Deftones he released the albums Diamond Eyes (2010) and Koi No Yokan (2012), and is currently working on the band's eight studio album, Gore, which is set to release on April 22, 2016.
