The X legend begins with a 1981 gig. A drunk driver killed Singer Exene Cervenka’s beloved sister on a Hollywood side street minutes before the band went on-stage. In a flurry of grief and rage, X delivered a blistering set that defined the transcendent hope and fury of punk. Now, 37 years on, the fire may have dimmed, but the band’s legacy burns as bright as the burning letter X that graced the cover of their debut album.
