I think it depends what you're looking for.
The singer and I are researching this quite a lot at the moment. Generic things we've picked up (although this is with metal).
- Look confident, move with the music in general
- Look at the crowd / look around
- Adopt a wider stance than normal (was very odd to me too begin with but actually feel LESS of a pillock than before
- Interact with the environment, rest on monitors etc
- Interact with the rest of the band, move over to where the guitarist is playing, go rock out with the singer
- Know when to blend into the background so that you're not all competing for attention at once
- When walking across a stage (assuming your stage IS big enough to walk on) try to walk in time with the music
Would love for others to add to this list
