Patrick Nichols has been photographing Toronto’s hip-hop artists for decades. His latest photo, “A Great Day in Toronto Hip Hop,” features 103 key players from the scene captured all in one place. It’s just been put on display in the Art Gallery of Ontario’s new exhibit, “The Culture: Hip Hop and Contemporary Art in the 21st Century.” Patrick sits down with Tom Power to talk about the photograph, trading in a turntable for a camera, and his life in photography and hip-hop.
