This is an old clip from a performance on television(!) in the '70s. The piece is De Futura.
The long-haired drummer who keeps making faces is bandleader/composer Christian Vander
And a more recent clip, also from French TV. The piece is K.A. (Kohntarkosz Anteria), a piece that was written back in the '70s but never recorded until recently:
Vander's hair is shorter (and greyer), and he's a little chubbier than he used to be back in the day. But he still makes faces, and still tears it up on the kit.
