Obviously there is stuff that I wouldn't play in a club that I play at festivals, and vice-versa, but my sets are still dominated largely by my own music. I think that's what makes me stand out a bit. My music is also festival- and club-friendly, so it generally works out well.
There's an amazing intimate feeling in a small club but an insane rush playing a stadium or festival.
Playing a room, it's a real dictator-type situation - you can really move the crowd the way you want to. In a festival, there's a sea of people, and it's harder to lock in on any one group.
