Today brings another step forward with "Buzzkill(er)." The track is a sonic continuation of "Rough Detective," the last new song heard from the supergroup back in January, and, before that, "Open Up (That's Enough)."

It's rough-edged, punk-spirited and, on it, frontwoman Alison Mosshart's vocals cutting like a razor blade. When "Rough Detective" and "Open Up" were released, Jack White's Third Man Records said of the tracks in a press release that they're "unlike anything else the band has ever done and are both ample reminders of the ferocity of this motley collection of low-lifes, grifters and ne'er-do-wells. These songs are not throw-aways. These songs are not demos. These songs are not outtakes."
