"Hi. We're blink-182. This past week there’ve been a lot of questions about the current status of the band, and we wanted you to hear it straight from us. To put it simply, We're back. We mean, really back. Picking up where we left off and then some. In the studio writing and recording a new album. Preparing to tour the world yet again. Friendships reformed. 17 years deep in our legacy.
