Twenty years ago, the Grammy Award winning pop-punk trio Green Day released “American Idiot” — their ambitious rock opera, a treatise on a world power in decline written by a band with cultural clout and consequently, political power. (It was angry and smart, and most importantly, hook-heavy — the catchiness no doubt a driving factor in its Broadway adaptation).

“American Idiot” ushered in a new generation of loyal listeners — in some situations, the children of the initial fans who account for one of the over 10 million sales of their 1994 album “Dookie” — offering a familiar language of dissidence for a generation just old enough to remember 9/11.

In short: time moves on, but Green Day remains ferocious, allowing their listeners the opportunity to put language and music to their frustration. The targets of their ire are always the same: war, systemic injustices, political pundits. And on their 2024 album, “Saviors,” their weapons are once again drawn.

“Saviors” kicks off with the spirited rock ‘n’ roll of “The American Dream Is Killing Me,” taking aim at a litany of sociocultural issues in lyrics like “People on the street/ Unemployed and obsolete,” delivered in frontman Billie Joe Armstrong’s immediately recognizable nasal snarl.
