When founding guitarist and singer Tom DeLonge left Blink-182 in 2015 to pursue other interests (including becoming one of the world’s foremost UFO experts), the band replaced him with Alkaline Trio’s Matt Skiba. Now that DeLonge is back in Blink, Skiba is getting the boot, much like Josh Klinghoffer when John Frusciante returned to Red Hot Chili Peppers.
