Watch this short about biases towards drummers video: https://www.youtube.com/watch?v=OzpCiXuWcHs ....where drummer/composer Tyshawn Sorey seeks to dispel that image. Listen to what he has to say, then come back and discuss any related topic e.g. your impressions, what surprised you, what YOU think the contemporary musician should know (e.g. is it important to know something about the piano, as Tyshawn suggests?)
