“Mardi Gras music” is generally defined as the time-honored standards of the Carnival season: “Mardi Gras Mambo,” “Carnival Time,” “Go to the Mardi Gras,” “Second Line Pt. 1,” “Big Chief,” “Do Whatcha Wanna,” etc. But this weekend in New Orleans, any live music is “Mardi Gras music.” From parade routes to block parties to the wee hours in nightclubs and music venues, the good times will roll to a soundtrack as diverse as the city itself.

Here’s a guide to the sounds of Carnival time:

Maceo Parker

11 p.m. Friday, Tipitina’s, $35

Is there a living saxophonist with a more impressive funk resume than Maceo Parker? He made key contributions to recordings and/or tours by James Brown in the 1960s, Parliament/Funkadelic in the 1970s, and Prince in the 2000s. He anchored Brown’s JB Horns on such classic albums as “Say It Loud, I’m Black and I’m Proud” and “Sex Machine.” With George Clinton and P-Funk, he lit up “Mothership Connection” and more. Prince recruited Parker for “Musicology,” “3121” and other latter-day albums. For the past 20 years, Parker has also toured and recorded with his own ultratight band. They hit Tipitina’s on Friday; local alternative cellist Helen Gillet is also on the bill.

Big Freedia and Sweet Crude

10 p.m. Saturday, One Eyed Jacks, $35

In what has become a newfangled Carnival weekend tradition, Big Freedia, the ever-colorful Queen of Bounce, shares a bill with Sweet Crude, the ambitious local modern rock band that alternates English and French lyrics. Reality TV star Freedia taught the world to twerk. She and her dance team are outrageous on a normal night; imagine what might be in store Mardi Gras weekend. Freedia canceled some recent shows in the wake of her brother’s death, but is ready to get back to work for what will be a big weekend (she returns to One Eyed Jacks on Sunday). Sweet Crude is fronted by powerhouse vocalist Alexis Marceaux; she and her bandmates are influenced by everything from Fleetwood Mac to the music of southwest Louisiana. Sweet Crude is also at One Eyed Jacks on Friday.

Shovels & Rope

11 p.m. Sunday, Tipitina’s, $27

Shovels & Rope husband and wife duo Michael Trent and Cary Ann Hearst will bring a hootenanny to Carnival. Together, they deploy guitars, harmonicas and a stomping style of percussion to make modern-day Appalachian music, equal parts folk, rock ‘n’ roll and old-school country. Their lyrics occasionally have a historical bent; the song “Thresher” was inspired by the 1963 sinking of the nuclear attack submarine USS Thresher. Indicative of their diversity, in New Orleans they’ve performed at both the Americana-leaning Hogs for the Cause and the rock/rap/EDM-focused Voodoo Experience. They’ll headline the Sunday night blowout at Tipitina’s following the Bacchus parade, a job Trombone Shorty & Orleans Avenue previously held for nine consecutive years.

Alexey Marti

8 and 10 p.m. Sunday, Snug Harbor, $15

Percussionist Alexey Marti moved from one highly musical city to another. A native of Havana, he came to New Orleans to study jazz at the University of New Orleans. His Afro-Cuban hand-drumming skills won him first place in the prestigious Thelonious Monk Jazz Institute’s competition. During his years in New Orleans, he has performed with a variety of ensembles, fusing modern New Orleans jazz with rumba and other styles he brought with him from Cuba. The speed with which his hands work the congas is as impressive as the structure he maintains within those rhythms.

Big Gigantic

10 p.m. Sunday, Joy Theater, $27.50-$40

Big Gigantic is an instrumental duo whose electronic music draws heavily from jazz and hip-hop and is enhanced by an immersive production highlighted by an ever-evolving light show. Based in Boulder, Colorado, Big Gigantic consists of saxophonist/producer Dominic Lalli and drummer Jeremy Salken. Their most recent album, “Brighter Future,” is available in a predominantly teal tie-dyed vinyl version. They’re a favorite on the festival circuit, having appeared everywhere from Coachella to Hangout to Bonnaroo. Every September since 2012, they’ve presided over their own popular Rowdytown festival at Red Rocks Amphitheater, not far from their base in Boulder. They bring their Got the Love Tour to the Joy Theater on Sunday; Shallou and Dino Brawl are also on the bill.
