The band is the brainchild of former Special Needs frontman Zachery Stephenson, London singer-songwriter Andy Potter and former Queen Kong chanteuse Amy Fox, joined by Italian guitarist Davide Ragazzo, French drummer Elian Dalmasso and bassist Patrick Balfe (the latter three, also accomplished solo performers).

With five lead singers, four nationalities and an infinite amount of songs Arms are not restricted by the conventional boundaries that most bands face.
The band's style hints at The Strokes and Arcade Fire but incorporates wider influences.
