Sweet soul music warmed the crowd in the comfortably-filled Newport Music Hall on Tuesday night, courtesy of Black Pumas. The Austin band led by singer Eric Burton and guitarist Adrian Quesada is touring in support of its self-titled debut, which has garnered the band a Grammy nomination this year for Best New Artist.

The solid four-piece band backing Burton and singers Angela Miller and Lauren Hornsby was tight and intuitive. Quesada added psychedelic-accented guitar solos to tunes such as “Stay Gold,” bassist Brendan Bond drove the filtered ‘80s funk of “Mrs. Postman,” and drummer Stephen Bidwell kept the groove fluid but deep. Keyboardist Jaron Marshall not only lent fine detail throughout but joined Burton in a duet of Tracy Chapman’s “Fast Car” for the first encore.

The group and three singers acted as co-conspirators in a mission to make believers, not only in their fresh take on classic soul, but the songs, which were filled with romantic desire and positive vibes. With considerable skill, they delivered floating jazz grooves, vintage funk, and psychedelic soul.

It all came together, though, in Burton’s ability to connect with a sometimes-electrifying performance. If he forced the issue at the start by repeatedly saying hello to the city by name and then inserting “Columbus” in a song several times, he built a more genuine relationship as the evening continued. On “Know You Better” he held back for a time in the middle before building the crescendo to a fever pitch at the end with the backing singers wailing in fits.

The wiry, dynamic singer has a style of his own, even though there were suggestions of a few classic soul stars in his delivery. He repeatedly slipped into falsetto at the end of phrases as easily as Al Green; during “Stay Gold” he recalled Bill Withers for a moment.

For a group with just one album under its belt, Black Pumas made a night of it, performing most of the album as well as several non-LP tunes.

Shreveport’s Seratones opened with a short set as reverential of soul and pop tradition but equally fresh and unique. The band’s persona, like that of the Black Pumas, was carried by its lead singer, the ebullient A. J. Haynes. With a stage demeanor as friendly and spontaneous as Erykah Badu, a puffy orange chiffon skirt and gigantic Afro, and a vocal delivery something like a bluesy Diana Ross, Haynes led her band on its own interpretation of Phil Spector-styled pop, Northern soul, and doo-wop.
