The Weeknd

The 'Blinding Lights' hitmaker turned to psychedelic substances during the early stage of his career - and it had an impact on his music composition.

He told the Guardian newspaper: "When I had nothing to do but make music, it was very heavy. Drugs were a crutch for me. There were songs on my first record that were seven minutes long, rambling – whatever thoughts I was having when I was under the influence at the time. I can’t see myself doing that now."
