In November, local musician John Spalding passed away after a long battle with lung cancer. To help Spalding's family pay off the remaining medical bills, at least half a dozen benefit shows have been organized in his honor. Tonight's impressive installment—which features Minus the Bear, the Cave Singers, Rocky Votolato, Past Lives, and Triumph of Lethargy—will be a bittersweet celebration of a beloved man and a reminder of the talent and generosity of Seattle's tight-knit music community.
