Sarah McLachlan Is Resurfacing

The Canadian songwriter became a superstar through a series of defiant decisions. After slowing down to be a single mother, she has returned to the stage and studio.

Sarah McLachlan was just 30 hours from beginning her first full-band tour in a decade, and she could not sing.

She was in the final heave of preparation for eight weeks of shows stretching through late November that commemorate “Fumbling Towards Ecstasy,” the sophisticated 1993 album that turned her into an avatar for the sensitive, mysterious singer-songwriters of ’90s radio. But three days into a string of seven-hour rehearsals, her voice collapsed, the high notes so long her hallmark dissolving into a pitchy wheeze.

So onstage in a decommissioned Vancouver hockey arena, a day before a sold-out benefit for her three nonprofit music schools, McLachlan only mouthed along to her songs, shaking her head but smiling whenever she reached for a note and missed.

“It only goes away when I project, push out,” she said backstage in a near-whisper following the first of the day’s mostly mute run-throughs. She slipped a badge that read “Vocal Rest” around her neck and winked. “Luckily, that’s only a third of what I do.”

For the last two decades, McLachlan, 56, has contentedly receded from the spotlight and the music industry she helped reimagine with the women-led festival Lilith Fair. Since 2008, she has been a single mother to India and Taja, two daughters from her former marriage. With rippling muscles that suggest a lean triathlete, she is now a devoted surfer, hiker and skier who talks about pushing her body until it breaks. Though she writes every morning, waking up with a double espresso at the piano in her home outside Vancouver, she has focused on motherhood and the Sarah McLachlan School of Music, offering free instruction to thousands of Canadian children since 2002.

A few years ago, she finished a set of songs about a pernicious breakup but reckoned the world didn’t need them; she hasn’t released an album of original material since 2014. “What do I want to talk about?” she said months earlier during a video interview from her home, swaying in a hammock chair. “I’m just another wealthy, middle-aged white woman.”
