I'm a massive Nick Cave fan and had to look this up. I found this, which is a pair of letters from him.

It struck me while writing this how much more powerful a statement you could make if you were to go to Israel and tell the press and the Israeli people how you feel about their current regime, then do a concert on the understanding that the purpose of your music was to speak to the Israeli people’s better angels. That would have a much greater effect than a boycott.

I dunno. I can see his point but I'm also disappointed? It's definitely not "staunchly pro-Israel". He's just made a decision to play there and is using that to justify it. I don't know if showing up and telling people in person is better than boycotting and showing them what they're missing. If I were in his position I'd boycott.
