The first thing to know about a Foo Fighters show is that there are virtually no breathers. Even the acoustic numbers are intense and if you can’t handle three hours where the passion and the energy never let up, you came to the wrong place.

In terms of mood, Sunday night’s Fenway Park show was nearly the opposite of the Foos” show at Boston Calling last year. At the time the band was still aching over the recent loss of drummer Taylor Hawkins, and the show had a slightly somber, memorial vibe. Hawkins was hardly forgotten this week, as his favorite Foos song “Aurora” was played in his honor while he drummed on video. “I like to think he’s still here with us on nights like this,” frontman Dave Grohl said.

But this show was far more of a celebration. Just two songs in, “No Son of Mine” was stretched into an homage to classic arena rock, complete with borrowed Sabbath guitar licks from Pat Smear. More than two hours later, Grohl invited the audience to scream their heads off on “Monkey Wrench” and then said “Now I’ll show you how the professionals do it,” ripping his own throat to shreds. New drummer Josh Freese, who respectfully held back a little at Boston Calling, was in full powerhouse mode this week, going wild with rolls and fills. He even paid tribute to one of his previous bands, Nine Inch Nails, with a bit of “March of the Pigs” during the band intros.

Though the volume seldom flagged, they did cover a handful of musical bases. “My Hero” was all arena-rock grandeur, starting slow and building strong. “This is a Call” represented their grunge-inspired roots, “Learn to Fly” (with the loudest of the night’s many singalongs) their more poppy side. A brief acoustic spot found keyboardist Rami Jaffee strapping on a squeezebox for “Skin & Bones.”  As Grohl noted, “Nothing says stadium rock like a dude with an accordion.”

That’s about all the Grohl stage patter we can quote directly, since the man is not PG rated. But he did recall playing Fenway with a broken leg in 2015, saying the wheelchair bound show was one of his all time favorites, and revealing what he was really sipping from his water bottle that night.

One of the musical high points was saved for the encore. The ten-minute, multi-part “The Teacher” — written partly for Hawkins and partly for Grohl’s late mother — was the biggest surprise on the latest album “But Here We Are,” and they expanded on it live — riding the song’s frantic opening section into its cosmic prog middle and reflective finale. This piece bore traces of every great Foo Fighters song, including a few that haven’t been written yet.

Either of the opening bands could have blown a lesser headliner off the stage. Australian punks Amyl & the Sniffers packed plenty of manic energy into their 30-minute slot, fueled by the striking presence of frontwoman Amy Taylor. And for pure high spirits, Swedish garage band the Hives were hard to beat. They borrow the hooks and swagger from the ‘60s punk and soul that they clearly love, but add their own unique sense of humor, as frontman Howlin’ Pelle Almqvist becomes a one-man cheering section for his own band. One of their new tunes, “Countdown to Shutdown,” may be the first in history to make the COVID pandemic sound like fun.
