Anyone Googling on a Vainberg-Shostakovich connection would probably
find the following website, the content of which is an interesting

"The Seventh Symphony is a fascinating instance of Vainberg and
Shostakovich treading so closely in each other's footsteps that
it is hard to distinguish who is following whom."
