Seattle Mayor Jenny A. Durkan has declared tomorrow, August 11, 2018, to be “Sub Pop Day.” In a proclamation issued earlier today, Durkan wrote that “the influence of Sub Pop helped establish Seattle as an international music destination,” and also cited the record label’s “long history of challenging the cultural mainstream in irreverent and often hilarious ways.” Check out the full proclamation below.

“Every day is a perfect day to celebrate music and art but to have an actual ‘Sub Pop Day’ celebrated in Seattle is the best!” Sub Pop CEO Megan Jasper said in a press release. “We’re eternally grateful to call Seattle, this incredible city of music, home.”

August 11 is also the date of Sub Pop’s SPF30 festival, celebrating the label’s 30th anniversary. Various artists including Father John Misty, Beach House, LVL UP, Hot Snakes, and more are set to perform. Alaska Airlines recently unveiled a Sub Pop-branded airplane to celebrate the anniversary.
