AC4 is led by Dennis Lyxzén, best known as the singer of REFUSED and THE (INTERNATIONAL) NOISE CONSPIRACY, supported by guitarist Karl Backmann, bassist Christoffer Röstlund Jonsson and drummer Jens Nordén, all Umea hardcore mainstays from bands like STEP FORWARD, D.S.-13, REGULATIONS and THE VECTORS.

Together they have perhaps more than 100 years of experience in HC/punk bands.Burn The World" is AC4's second album.

It contains 16 songs of classic hardcore punk á la early 80s, similar to DEAD KENNEDYS, BAD BRAINS and G.B.H., mixed with a pinch of MOTÖRHEAD.

In other words: the music the band members grew up with. The band formed in 2008, released their debut album and toured throughout Europe and Australia in the following years.

During REFUSED's first reunion tour in 2012, AC4 took a break from live performances and focussed on recording the 'Burn The World' album.

AC4 was folled by Dennis Lyxzén's next band project INVSN, still active.
