Well, these deaths hit hard.
Frederic Rzewski (just saw him in 2017 with
Musica Elettronica Viva and solo)
and
Peter Zinovieff (influential engineer: EMS studios introducing the VCS3 synthesizer to lots of major rock bands).
When I saw these, it showed that they died on the same day - today -
but seconds later it showed
Zinovieff dying three days ago.
Both people very important to their professions.
