A few years ago, Mustafa released his critically acclaimed EP, “When Smoke Rises,” which chronicled the deaths of loved ones from his community of Regent Park in Toronto. So when he sat down to write his debut album, “Dunya,” the Juno-winning musician and poet wanted to explore other things, like love, faith and his relationship with God. Then his older brother died. Mustafa sits down with Tom Power for a wide-ranging conversation about his latest album, the loss of his brother and why Toronto no longer feels like home to him.

When Nick Cave was in his early band The Birthday Party, he was angry and antagonistic toward his audience. The legendary Australian musician, writer and actor eventually grew out of his youthful contempt, but he remained consumed by his work, always putting it first before anything else.

He also discusses his new Nick Cave and the Bad Seeds album, “Wild God,” and the mysterious origins of his songwriting.

When the Canadian indie rock band Casper Skulls got their start about 10 years ago, things were a little different.

Melanie and Neil join Tom Power to talk about making their latest album, “Kit-Cat,” through those major life changes — and why it might be their best record yet.
