My War was released after a long period where the band could not release any albums due to a legal dispute with Unicorn Records.
The first six songs on the a-side of My War are similar to the material on 1981's Damaged, but the three songs on the b-side proved that Black Flag was moving away from the band's early, fast-paced material. The b-side songs are played at about half the pace of the band's earlier material, each clocking in at over six minutes, and display a doomy, ominous sound indebted to Black Sabbath. My War is generally cited as being a major influence on many bands in the sludge metal and grunge genres. Two of the songs featured on the album are solely written by Chuck Dukowski (My War, I Love You) though he was no longer a member of the band by this point and does not perform on the album.
