Brent Michael Kutzle (born August 3, 1985) is an American musician, multi-instrumentalist, songwriter, record producer, and film composer originating from Fountain Valley, California.

Much like OneRepublic's lead vocalist, Ryan Tedder, Brent has also written and performed with various other musicians from both underground music scenes and mainstream acts, including Beyoncé, Matchbox Twenty, Ellie Goulding, Cobra Starship, Leona Lewis, Kelly Clarkson, ísland, Vermeer, Augustine, This Allure, Monarch, Venus Infers, Jessica Dobson, and Kevin Max.

Kutzle has transformed the sound of the cello for a rock band by using delay, reverb and looping effects.

In addition to playing the cello and the bass guitar, Kutzle, along with guitarist Zach Filkins, also aids friend and frontman, Ryan Tedder, in songwriting and composing music for the band.

At live concerts, he can be seen playing bass guitar, cello, and singing background vocals alongside Filkins, drummer Eddie Fisher and guitarist Drew Brown.
