Matthew Bellamy of the English band Muse has cited Morello as an influence, which can be heard in his use of pitch-shifting in solos.
Morello and Serj Tankian of System of a Down are the co-founders of Axis of Justice, a political group whose declared purpose is "to bring together musicians, fans of music, and grassroots political organizations to fight for social justice together." They "aim to build a bridge between fans of music around the world and local political organizations to effectively organize around issues of peace, human rights, and economic justice."
