It was a generous, generally rocking show on a wide stage, where equipment, amps and guitars spilled clear down the runway to backstage. The volume was that of someone used to arenas and stadia as well (or someone who had already lost their hearing at such venues).

Though fans were rewarded deep in the set with Petty classics — five in all before it was all over, including the tour debut of “American Girl” — the Dirty Knobs material was well-received throughout. Given a chance to request songs, one fan insisted on their “Sugar” to begin a long, cover-heavy encore set. 

Andhe hooked those unfamiliar with the tunes early on with a singalong to “Lightning Boogie.” Having been a part of Petty’s crowd-pleasing Heartbreakers for four decades, he’s picked up a thing or two about stagecraft. 

The Knobs are a solid outfit with hard-hitting Matt Laug, bassist Lance Morrison and guitarist Jason Sinay, who trades off on solos as well as providing key backing and occasional lead vocals for Campbell, whose own vocals, as close as they are to Petty’s, can be a little thin. 

Thinner still are the lyrics to a lot of Knobs songs — “Seven come eleven, you’ll never get to heaven” goes one verse in his “Rat City.”

Clearly, Campbell was known for writing the music to Petty collaborations, and in the few songs that concentrated on longer solos or guitar interplay with Sinay were the highlights. 

The lyrical contrast was most obvious when he’d kick into something like “Southern Accents,” which like a few of the Heartbreakers hits, was done slower and quieter than the original, in part to bring out the words but also probably to avoid full scale nostalgic singalongs. Along these lines, “Refugee,” with a preface about the current Eastern European crisis, was especially effective. 

By the time they got to the encore, it was time to not only present Petty hits at the original tempo, but to throw in all manner of covers that showed off Campbell’s influences, from the Byrds’ reading of Dylan’s “I’ll Feel a Whole Lot Better,” to “Little Queenie” from Chuck Berry, whose music played before the band took the stage.

“You Got Lucky” was without the snaking keyboard riff Campbell tried to replicate on guitar, but it did have an astounding solo that wandered into all manner of recognizable Beatles riffs from “Eleanor Rigby” to “While My Guitar Gently Weeps,” some Ventures twang of “Walk Don’t Run,” some Dick Dale surf chops, licks of “Layla” here, a remnant of “Rhiannon” there. In short, the best kind of showcase for a guitarist.

Navigating through rock history also came in the final song, a version of Bo Diddley’s “Road Runner,” that led to his “Who Do You Love” to a bit of the Allman Brothers’ “Mountain Jam” to Cream’s cover of Skip James’ “I’m So Glad.”

It put the end of the show at well past 11 — a shockingly late hour for Birchmere fans who arrive as early as 6:30 to get a good seat are not surprised by shows ending as early as 9:30.

The evening began agreeably enough (at 7:30) with a set by Jeremy Ivey, a Nashville-based singer songwriter who immediately endeared himself to the audience by explaining his left hand was swollen because of a fall on a Baltimore street earlier that day that also gave him a bump on the noggin.

That made it tough to play F minor especially and he winced a bit through a modest set by a songwriter so prolific he was debuting one song he had written the night before. Married to Margo Price, the alt country star who collaborated with Campbell on a song on the new Dirty Knobs record, Ivey’s songs were full of interesting imagery and attitude, such that maybe he should be on the list to collaborate with Campbell for the next Knobs studio effort.
