A spectrum of American-roots music, brought forth with adult-contemporary sensibilities, was on display Saturday night when Bonnie Raitt and Lyle Lovett teamed for a double bill.

        A 12-piece band provided the Texas-swing foundation for Mr. Lovett's music, but the set was dominated by gospel stylings, and he threw some bluegrass, country, blues and rockabilly — albeit rockabilly executed in his usual relaxed manner — into the mix, as well.

        Ms. Raitt, who went on last, reached as far and wide stylistically as Mr. Lovett. The blues belter and slide guitarist extraordinaire thanked the crowed for “coming out to support roots music,” even though people's reasons for attending were less about making some sort of roots-music statement than just wanting to hear stuff like “Have a Heart,” “Thing Called Love,” “Something To Talk About,” and “I Can't Make You Love Me,” all of which she played.

        Still, the wide scope of the night's music was a big theme with her. “Between Lyle Lovett and myself we've got every type of music nabbed,” she said as an introduction to her concert staple of “Angel from Montgomery.” “So,” she joked, “I'm gonna do a speed metal version of this John Prine song just to round things out.”

        In addition to her blues-rock and pop repertoire, the 52-year-old singer's set featured New Orleans funk, Memphis soul, and “Silver Lining,” her new album's title track, written by Welsh singer-songwriter David Gray.

        Mr. Lovett limped out for his set. His right pant leg was split open on the side to make room for some sort of metal brace, necessary because of a leg fracture he suffered on his Texas farm in March when he was trampled by a bull.

        So he sat for his show, and it's not like he's the jumping-around sort anyway, so it didn't affect anything.

        Much of the set was made of more-recent material, like the two new songs (“The Truck Song” and “San Antonio Girl”) included on the best-of anthology released last year.

        Encores were duet-time, and they provided highlights. Ms. Raitt came out to join Mr. Lovett on “You've Been So Good up to Now,” and he returned the favor, singing with Ms. Raitt on “Thing Called Love” and “Do Right Woman, Do Right Man.”
