Moscow Five

As somebody who started following competitive league relatively recently, I sometimes feel as though I'm missing a bit of context in the scene as a whole. One of the things I'm most curious about is the old Moscow Five - I understand that they were one of the most dominant teams in the world for a time, but it's difficult to find actual tape of their play. It seems like a lot of tournaments of the day were less publicized than they are now, and it can be challenging to figure out "Oh, this was a big event, I should check that out" or "Oh, that was a 4 team invitational, it doesn't matter."

So - what were some of M5's most impressive performances? Were there any really impressive innovations that they developed that I could see on tape? I feel kinda lost when I try to research them or search for their games on youtube.
