Canadian singer/songwriter Sarah McLachlan made her mark in the late 1990s with a string of hits, including 1997’s “Building a Mystery,” and as one of the prime movers behind the Lilith Fair tour. In recent years, she’s been seen and heard primarily as an SPCA spokeswoman against animal cruelty. But she’s back with a new album, “Shine On,” written after a difficult period when a series of separations, including the death of her adoptive father, brought on writer’s block.

Saturday

Big History has been one of New Orleans’ better bands for finding the intersection of indie rock and electronic dance music. Recently, they announced on Facebook that singer Meg Roussel is moving to France and that this week’s show will be the band’s final performance. Big History is a reminder that young bands often break up for reasons that have nothing to do with the quality of their music, as demonstrated by their 2011 “All at Once” EP — still available for download from their website. Sweet Crude and Vox and the Hound open.

Sunday

When Justin Timberlake last played New Orleans, it was for swells attending a private corporate party as part of the Super Bowl festivities in 2013. At the show, he previewed a few songs from “The 20/20 Experience” with a biggish band and black suit and tie. Since then, he’s released the second half of “The 20/20 Experience”—“2 of 2”—and traded the classic stagewear for a more contemporary wardrobe and haircut. According to reports, what remains the same is the creativity and exuberance he brings to the show, freshening old songs in exciting ways and doing so with apparent ease.
