Cave is not the type of songwriter to sit around waiting for lightning to strike.
‘‘Inspiration is a word used by people who aren't really doing anything. I go into my office every day that I'm in Brighton and work. Whether I feel like it or not is irrelevant.''
I have only heard a little of Cave's music - and like what I have heard - but I see from his website that he is involved many fields. His books are listed at Goodreads.
