Wolves Riding Bears.

Claps, clicks and bumps and bums.
Cowbells, gang vocals and foot stamps.
Etc.

The trades of the nu-indie scenes seem to be based around just the simple enjoyment of little things.
Clapping along.
Little games, such as that of Dananananananananananananananykroyd's 'Wall Of Hugs' in place of the typical 'hardcore' 'don't label me' scene kid scene of the 'Wall of Death'.
They don't take themselves seriously.
It's more about enjoying oneself with progress, experimentation and basically, having fun.
Nu-Indie, encompassing Math Rock, Fight Pop, Math Pop, and the general resources of danceable Indie.
It's fun just to enjoy making music and performing arts.
Also, fuck four chords.
It's now all about being technical and yet still jumping about whist playing.
Also, include the bassist a bit.
Don't leave them playing the same chord for several metres.

Jumping is fun.
Jump into the crowd and involve them.
Make them do things.
Make them carry you while you play.

Play as many instruments as you can.
Get a cowbell and stick and hit it to the beat.
Play around with a keyboard once in a while.
Maybe get your laptop, hook it up and play some samples.
Just go mental.

Experimenting is fun.
