Since first emerging from (and defining) the Southern California pop-punk scene in 1978, the legendary Descendents have released classic after classic, from their landmark 1982 LP Milo Goes to College to 2016’s Hypercaffium Spazzinate. Now, after issuing a flurry of singles to get fans through the past few years, the band — Milo Aukerman (vocals), Bill Stevenson (drums), Stephen Egerton (guitar), and Karl Alvarez (bass) — will be touring in support of a new album. With a very cool twist.
