Evolving isn’t always easy—ask the Ramones, who unapologetically made the same record from cradle to grave.

Mad respect, then, to the Pack A.D., whose records today make it hard to believe that the duo originated as throwback-blues traditionalists.

Consider the band’s new single, “So What”, where singer-guitarist Becky Black and drummer Maya Miller find the sinfully sweet spot between shimmering ’90s shoegaze and hyperlush pop. Which is to say that the Pack A.D.’s Thursday-and-Friday stand (May 12 and 13) at the Cobalt won’t sound anything like the songs from Funeral Mixtape. Or, for that matter, the Ramones.
