TV producer looking for cool stuff to do in Tokyo

Hi everyone!  I'm a US television producer working on a Travel Channel show that may be filming in Tokyo in May.  We want to do cool, cutting edge, even seedy and underground stuff in addition to a couple of typical tourist things.  But I really need help in finding out what's going on in the worlds of art, music, nightlife.  If anyone has any advice, please post.
Thanks,
Toni

You can always try the host / hostess bars, but you may need to call in advance and negotiate with them if you're planning on filming them. Good luck.

Thanks!  We are definitely looking into that!
