"Nick Cave is one of these very rare male artists that has managed to hold my attention and interest over the course of four decades now. He is extraordinary and continues to push his artistry and has never cheapened himself or been a desperate gambler in Vegas. In regards to his musical career, he's always just done what he does, so beautifully, with no compromise to the musical climate. As a result, [he] has created his own genre, really, that he is king of. His career is just continuing to blossom and continuing to grow. It has this incredible reach now and is touching new generations. 

 He is one of the greatest artists, storytellers and musicians that I have ever met and have ever been around. I feel lucky to be here to enjoy his work and I'm so grateful that somebody like him is out there still. He is this incredible answer or rebuke to the current climate of just completely vacuous people-pleasing pop music. 

 He's a truly incredible wordsmith too and he is really blessed with the true greatness of a writer. He's not a pop lyricist by any stretch of the imagination: he's a great erudite communicator and you can feel that in his music, in his lyrics, in his books, in his scripts. He's bordering bona fide genius with his words – just so poetic and so very honest and authentic. 

 Each record is a logical sort of expansion from the previous record, but he's a great storyteller, and a great communicator, and a great connector too. I can't think of anyone else who has the kind of career he has, where he's never had a hit – not really, in the traditional sense of a hit – and yet enjoys this phenomenal career where he's now selling out fucking arenas around every corner of the world. I mean, it's mad. 

 He's so unique and just doesn't sound like anybody else. He's got this phenomenal band too in The Bad Seeds whose musicianship is just incredible. It's like going in to listen to an orchestra because it's so emotive and powerful: to see him live is truly extraordinary."

"She's one of my all-time favourite artists, all-time favourite spirits and one of my all-time favourite voices. I think she's incredibly fragile and I continue to worry for her because I don't think she's being very well taken care of as an artist. There's certain artists need everybody's help to continue to be creative and she's one of them. 

 I'm a tank – I can take care of myself and I don't need anybody's help, but Sinéad O'Connor is a jewel and has a voice like no other – one of the great voices of this century. I worry that we're going to lose her. She has mental health problems and has spoken very openly about them and is really brave and courageous for doing so. She's a great rebellious spirit who was punished for being a rebel in ways that we can barely imagine or conceive of. I have nothing but great admiration for her. 

 She has this extraordinary voice that just does things to my insides. She's a complete iconic gem and touches me in ways that so few can; she's made so many beautiful records. I wish I could sort of throw myself at her feet, because I feel like she finds love, I think, difficult to absorb, and yet she's so deserving of it. This voice comes, again, from a different universe. Its spectacular ability to both emote and communicate. I'm so grateful to her for this record; I just love it and I love hearing her sing so much. She's one of my touchstones, someone I always can rely on to bring magic. 
 When greats die, like when David Bowie died, there's this great outpouring of grief as I know there will be if and when, god forbid, we lose, finally, an artist like Sinéad O'Connor. Yet she's alive now and is capable of producing these spectacular pieces of work, and yet she's treated so brutally by the music industry – an industry who would rather laude in applause an uncreative, stage-schooled kid who's got a great voice but no soul. They'll get more excited about that than they will the possibility of signing a great like Sinéad O'Connor. And therein lies the ludicrousness of the modern music business."
