JJ Wilde comes by her surname honestly: Since 2019, the Kitchener, Ontario singer has been bringing a brash, bluesy, hell-raising spirit back to the FM dial. Her calling-card single, “The Rush”—which made her the first woman to simultaneously top the modern, active and mainstream rock charts in Canada—epitomises her tough-as-nails attitude. Over the song’s handclapped Black Keys swing, she recounts last night’s vices in a feisty fashion that blurs the line between cautionary and celebratory. And with the gritty Southern-fried gospel anthem “Mercy”, she channels her bad-ass energy into a dramatic revenge fantasy directed at domineering men.
