Great sounds without a conductor! Big band jazz has been doing this for a century or so, and it’s de rigueur for free improvisers, but we don’t often think of classical musicians performing without that person up there waving a stick. Enter Orpheus. (spoiler: jazz/pop/classical musician Branford Marsalis makes an appearance in the later vids.)

This is a great video, not only for its ideas and the excellent music, or copious evidence that musicians (even classical musicians, gasp) are funny people. Right up front, you see musicians talking about, and practicing, and they use their bodies (and words) to convey musical ideas. It’s a form of mental practice that veterans use without thinking about it. Maybe you can incorporate some of these ideas into your own practice.
