In 1993, three young boys were murdered in West Memphis, Arkansas. In what was widely considered a witch hunt, three older boys were convicted of the killings. Ten years later, Henry Rollins used his considerable cultural chops to raise money for their defense fund and for DNA testing, which could help clear them. His vehicle? The acclaimed CD “Rise Above” and a world tour. Broken Summers details the rehearsing of Black Flag songs he hadn’t played in years, dealing with an arrogant manager or two, a diverse group of musicians, recording the CD, and the arduous trek from Tucson to Tokyo that included grilling by heartland shock jocks unsympathetic to his cause. The book covers 14 months of desperate lows and dramatic highs, all rendered in Rollins’s trademark combative style. Included are black-and-white photos of the rehearsals, recording sessions, and tour.
