Here's a video of Debora Petrina (who describes herself as a "polymorphic artist") filling the silences in the music of Morton Feldman with distracting movement - and later accompanying herself on the drum.
I fear this is a good example of the global decline in attention span.
I found this Feldman workout video at Sequenza 21 which asked "Who says you can't dance to Morton Feldman?" More people ought to say that. Speaking of distracting movement during performances - here's a 1960 video from Dutch television. This rock 'n roll band has their moves down. Watch for the drummer walking around during his solo - all while keeping the beat. Gasp as the lead guitarist stands upright on the recumbent bass while playing a solo behind his back. Much more exciting than a dancing Morton Feldman pianist because there are no uncomfortable silences to fill.
