Blink-182 dropped an unconventional teaser on Wednesday via social media, revealing the release date for the trio’s next single, “Darkside.” The band shared a phone number on Twitter along with a photo of a message written in marker that read, “call for a good time.” A second tweet followed a few hours later, this time prefacing the number with the caption “Friday,” and a graphic reading “Darkside.” When you call the number, a 15-second clip of the new track plays. Fans can also text to receive a link to the teaser. The new song will be the fourth previewed from Blink’s upcoming eighth album, following “Happy Days,” “Blame It On My Youth” and “Generational Divide.” The yet-to-be-titled set is out September 20th. The number is 323-831-0182.
