Phil and Tim Hanseroth

The Hanseroth Twins

The Hanseroth Twins are a musical duo consisting of twin brothers Phillip John and Timothy Jay Hanseroth, artists, songwriters, and producers, best known for their work with Brandi Carlile.

The duo has been writing and performing together since 1990. They began their music career as vocalists and guitarists in their first band Ohnalim prior to creating The Fighting Machinists with two other musicians Miraslav Stephanov and Jim Whitney, and were signed to Interscope Records. After the members parted ways, the twins were introduced to local Seattle singer-songwriter Brandi Carlile by producer Rick Parashar in 1999, and the trio would later form the Brandi Carlile Band.

They were a part of writing and recording supergroup The Highwomen’s 2019 debut album, as well as Tanya Tucker’s 2019 and 2023 albums and wrote the score for Tucker’s 2022 documentary, The Return of Tanya Tucker.

The duo performs live with Brandi Carlile regularly, and have performed on the GRAMMYs and Saturday Night Live. They have performed backing up Joni Mitchell in the Joni Jams and Kris Kristofferson.

Phil Hanseroth is married to Carlile's younger sister, Tiffany, also a singer; Tim Hanseroth's wife is photographer Hanna Hanseroth.
