Christopher Joseph Baio (born October 29, 1984) is an American musician, best known for being the bassist for the New York City-based indie rock band Vampire Weekend.

Baio attended Columbia University in New York, majoring in Russian and Eurasian Regional studies and minoring in Math, graduating in May 2007.

During high school, Baio was lead guitarist, songwriter, and vocalist in a local Bronxville, NY, band known as Underrated.

Rolling Stone said, "A three-track set of undulating dance grooves that capture a vibe the bassist describes as 'hopeful melancholy,' it's the culmination of a hobby Baio took up half a decade ago as a student at Columbia University in New York."

Baio drew a lot of inspiration from electronic and dance music and spent much of the past year on DJing due to Vampire Weekend's light tour schedule, and he said, "I'd lock myself in my little office in my apartment with CDJs and a mixer and just practice mixing all day.

Though his earlier albums were pleasantly energetic – this one took a deeper and darker turn, being several octaves below his normal art.

"[13] Vampire Weekend also used The Beatles as an influence saying to Columbia University's alumni journalist "they played extremely popular music but at the same time drew upon Eastern and Western sources.

"[14] The band also has taken its style from a form of music called Afrobeat which is a mix between jazz, funk, and highlife, all cemented together by heavy traditional African influences.
