The photo collection

This photo, though water damaged shows a USSRPM technician experimenting with early version of "scratching" a record.
The idea was to reproduce the stuttering vocal of a tape loop but to be able to be performed live.

Here we see Ivan Egorov again experimenting with a sampling machine.
It is believed to be as large as the average lounge room in cubic metres and contained 15 tape reels

Ivanoff at the side panel of the machine inspecting tapes.
