R-Day is quintessential Seattle: it's quirky, it's fun, it's free, it's 21+, there's live music, and of course, there's Rainier. This year marks the tenth anniversary of the first R-Day, which celebrated the moment when Rainier Beer’s iconic “R” was restored to its place atop the Old Rainier Brewery in Georgetown. In addition to a herd of "Wild Rainiers," wacky merchandise, eclectic art, and more, there will be live music from truly incredible bands. Check out metal faves Helms Alee, the woman-fronted guitar grooves of Cherry Glazerr, and Seattle R&B powerhouse Parisalexa. KEXP DJ Larry Mizell Jr. will keep the party going between sets. by Shannon Lubetich
