AJJ (formerly known as Andrew Jackson Jihad) formed in 2004 in their home town of Phoenix, Arizona. Their early releases were marked by a folk punk production and themes covering mental health, poverty, and politics. However, with the release of Christmas Island in 2014 (soon followed by the name change), their genre became less defined. In the releases since, their sound is more varied, slightly veering towards the experimental.

The band’s core members are Sean Bonnette (lead vocals, acoustic guitar) and Ben Gallaty (bass guitar, double bass, backing vocals).
