Bob Mould has been releasing music since 1982, when Hüsker Dü’s hardcore album Land Speed Record introduced the cantankerous but melodically inclined rock star. After Spin Magazine forced Mould out of the closet in 1994, his life took a number of weird turns. He broke up Sugar, his post-Dü rock trio, and spent a year writing storylines for pro wrestling outfit WCW. He abandoned guitars and became a house DJ, running a monthly party called Blowoff for a few years. He wrote a memoir. He moved to Berlin. Eventually he went back to guitars, recently releasing his thirteenth (!) solo album and, uh, matching flannel shirt. Fall River’s the first stop on his national solo tour. Will Johnson opens.
