In this episode we're joined from Nashville by acclaimed critic, author and broadcaster Ann Powers for a discussion of her new Joni Mitchell book.

Starting in Ann's native Seattle, we hear about her early '80s pieces for The Rocket before moving on to her stints at the San Francisco Weekly and the New York Times. Mention of Piece by Piece, the 2005 book she wrote with Tori Amos, leads us to clips from Steven Daly's 1998 audio interview with Amos and a broader conversation about the wave of female singer-songwriters that engulfed pop music in the '90s.

Ann's noughties move to California and the L.A. Times prompts discussion of the "dreamlike" night she spent chez Prince on New Year's Eve, 2008. From there we jump to the life and music of an artist Prince admired more than most: Joni Mitchell, subject of Ann's remarkable new book Travelling. With particular focus of 50-year-old jazz-rock masterpiece Court and Spark, we explore the richness and complexity of Joni's '70s work, her deep engagement with the Black American experience, and the worship she's experiencing in the wake of the recent "Joni Jams".

Many thanks to special guest Ann Powers. Travelling: on the Path of Joni Mitchell is published by Harper Collins and available now from all good bookshops.
