For much of the pop music universe, Sunday night's Grammy Awards are about whether or not Eminem's comeback becomes a coronation and how, exactly, Cee Lo Green's profane hit will be announced. But several Louisiana artists will vie for gold Gramophones in lesser-known categories. They include:

Troy "Trombone Shorty" Andrews. His first national release, "Backatown" (Verve Records), is nominated as best contemporary jazz album. Making the hometown connection even stronger, Galactic saxophonist Ben Ellman produced "Backatown." A win would be a career milestone for both.

Dr. John & the Lower 9-11. His latest CD, “Tribal,” is up for best contemporary blues album. In March, he will be inducted into the Rock ‘n’ Roll Hall of Fame.

Kenny Wayne Shepherd. The Shreveport guitarist’s “Live! In Chicago” will go head-to-head with Dr. John’s record for best contemporary blues album. It features north Louisiana axe-slinger Buddy Flett and longtime Bourbon Street bluesman Bryan Lee.

Wynton Marsalis. The New Orleans-born trumpeter is up for best improvised jazz solo for “Van Gogh,” from the Jazz at Lincoln Center Orchestra’s “Portrait in Seven Shades.”

The Cajun and zydeco category features an all-south Louisiana slate of nominees: the Pine Leaf Boys, Chubby Carrier, Feufollet, Cedric Watson et Bijou and D.L. Menard.

The first collection of music from acclaimed HBO series “Treme” features local singer John Boutte – who wrote and sang the song used as the show’s theme music – Kermit Ruffins, the Treme Brass Band, Irma Thomas and Allen Toussaint, Tom McDermott, the New Orleans Jazz Vipers, Donald Harrison, the Soul Rebels Brass Band with John Mooney and more. It’s up for best compilation soundtrack for motion picture, television or other visual melody.

Additionally, Steve Earle’s “This City,” the season-ending “Treme” song arranged by Allen Toussaint, is up for best song written for motion picture or television.

Tangentially, Randy Newman – who lived in New Orleans briefly as a child – is competing with Earle. His “Down in New Orleans,” from Disney’s “The Princess and the Frog,” is nominated.
