“Jane Says,” the alt-anthem that defines Jane’s Addiction, began in the seedy underground. The nearly five-minute pre-grunge track cleared the decks for flannel and combat boots to reach suburban malls. Jane’s Addiction straddled the space between alternative rock and Hollywood hedonism. The band’s 1988 debut Nothing’s Shocking became the first mainstream alternative rock album. They successfully fused the Los Angeles post-punk underground with funk and metal—the same scene that birthed the Red Hot Chili Peppers and Fishbone.
