Charlie joined the touring band for Bastille at the start of the 2015 Festival season. His first show with them was at the Caribana Festival where they also played some new songs. It is unclear at this point how long he will be touring with the band. He is a singer/multi-instrumentalist who has released his own music prior to being a part of Bastille's touring band.

More Stately Mansions is an LP he released under the name Charlie Barnes, although it was a band project, not a solo one. The other band members are Ste Anderson, Sean Balcombe, and Joshua Hughes. The LP was released on May 12th, 2015.

In early 2018, he released another LP titled Oceanography, featuring some backing vocals from Dan Smith.
