Greensky Bluegrass performs at Roanoke Island Festival Park on the Outer Banks on Sunday, Aug. 14. (Greensky Bluegrass)

Like most modern bluegrass bands, Greensky has one foot in the past.

On their website, the Kalamazoo, Michigan-based quintet describes their sound as “our own version of bluegrass, mixing the acoustic stomp of string instruments with the rule-breaking spirit of rock and roll.”

The lineup includes Michael Bont on banjo and vocals, Paul Hoffman on mandolin and vocals, Mike Devol on upright bass and vocals, David Bruzza on guitar and vocals and Anders Beck on Dobro.

Greensky Bluegrass, along with the Wood Brothers, performs Sunday, Aug. 14, at Roanoke Island Festival Park’s outdoor amphitheater in Manteo.

Since forming in 2000, the group has released 11 full-length albums, including this year’s “Stress Dreams.”

The quintet is known for their freewheeling live shows, mixing originals and covers (Allman Brothers, Pink Floyd, Grateful Dead, Prince, Lester Flatt and Earl Scruggs, Bill Monroe and The Beatles, among others).

And they’re not afraid to jam, often extending their tunes with traditional and non-traditional breakdowns.

Greensky is a virtual touring machine, and next month they’ll play three shows at the iconic Red Rocks Amphitheatre in Morrison, Colorado.

The Wood Brothers traffic in original music that merges folk, gospel, blues, roots, Americana and jazz with story-telling lyrics.

Chris Wood (upright bass and vocals), Oliver Wood (acoustic and electric guitars and vocals) and Jano Rix (piano, percussion and vocals) make up the band.

The trio has released 11 full-length albums since forming in 2004, including 2018′s Grammy-nominated “One Drop of Truth.”

When: 6 p.m., with doors opening at 5 p.m.

Where: Roanoke Island Festival Park, 1 Festival Park (across from the Manteo waterfront)

It’s lawn seating, so bring a chair or blanket.

On a recent Friday night, singer-guitarist Scott Sechman, 68, was playing a gig on the deck of an eatery on the Manteo waterfront.

About a dozen people were up-close grooving to the sounds; another 10-or-so folks along the boardwalk were digging the performance.

They quickly discovered the Southern Shores-based Sechman (pronounced Seck-man) is a musician with a sense of humor and adventure.

After playing a bluesy “Don’t Let Me Down” by The Beatles, he drew a few chuckles by labeling it “one of my originals.”

Though the singer-songwriter didn’t perform the tune on this night, he’s been known to cover Britney Spears’ 1990s dance jam “Oops, I Did It Again.”

Sechman, accompanying himself on an acoustic-electric Cole Clark guitar, then ascended to rarefied air for bar singers, knocking off aching remakes of Left Banke’s 1966 baroque-pop classic “Walk Away Renee” and Michael Nesmith’s 1967 folk gem “Different Drum,” as well an electrifying, improvised take on Bob Dylan’s 1967 classic “All Along the Watchtower.”

He plays three no-cover shows this week on the Outer Banks.

With his muscular guitar style and unique vocals, ranging from smooth to gravelly, Sechman, who moved from Southern California to the Outer Banks in 2015, doesn’t really sound like anybody else on the local music scene.

He uses a looping device, which allows guitar-playing options (strumming, finger-picking, bass and rhythm, all within one song).

“It gives me the freedom to jam,” Sechman explained later in a telephone interview.

His remakes are more like celebrations than copies, bringing out the best elements of the songs.

“Sometimes I fly by the seat of my pants,” he said.

Other highlights of the night included a rapturous version of the Rolling Stones’ “Paint it Black” and a fun, singalong cover of Neil Diamond’s “I’m a Believer,” made famous by the Monkees.

Sechman’s repertoire also includes Blind Faith’s “Can’t Find My Way Home,” Neil Young’s “Alabama,” Procol Harum’s “Whiter Shade of Pale” and a dozen-or-so tunes by The Beatles (“Norwegian Wood” and “Dear Prudence” are standouts).

Also at his fingertips are dozens of fine originals.

And what’s the music veteran’s key to success?

“I try to play to the audience that’s listening.”

When and Where: 5 to 8 p.m. Saturday, Aug. 13, at Lost Colony Tavern at 208 Queen Elizabeth Ave. in Manteo; 5 to 8 p.m. Tuesday, Aug. 16, at Uncle Ike’s Sandbar and Grill at 1159 Austin St. in Corolla; and 6 to 9 p.m. Thursday, Aug. 18, at Corolla Light Resort at 1197-B Franklyn St. in Corolla
