As promised, Blink-182 released a new song yesterday, "Up All Night." It's their first bit of original music since their last album, 2003's self-titled release, which was followed by a breakup partially resolved by Travis Barker's plane crash. Also, as promised, this new song's kind of weird! When bassist and co-front man Mark Hoppus explained that "we have songs that are madly different and experimental," you could have been forgiven for taking that with a huge grain of salt, coming, as it did, from the dudes who named an album Take Off Your Pants and Jacket. But within those self-adjusted parameters, "Up All Night" is still a bit of a curveball, just for not being the soothing pop-punk palliative you may have expected as the first comeback release. The verses have a spacey effect and bare bass line, familiar from early aughts single "Feeling It," but the verses shout out "lies" and "demons," and the guitar parts keep on slipping into a stomping hardcore riff. You can still sing along to the chorus, though, which is nice. Unresolved, though: What does this have to do with Christina Applegate?
