Brass Against are a collection of musicians who create "brass protest music that calls fans to action".

"In this politically challenging era, it’s time to stand up against the machine," say the band. "We want the music we perform to sound inspiring and resonate with people’s emotions, encouraging them to act. We combine rock and edgy hip-hop to play music that's powerful and empowering. Brass Against is exceptional music with a political edge."

The band recently recorded a version of Black Sabbath's War Pigs, with vocalist Maya Azucena.
