This is what MCZ's 2020 summer concert looked like.

For nine years in a row, starting in 2011, MCZ has held a large live concert in the summer. 
However, in 2020, due to the effects of the coronavirus, they had to give up live performances for an audience, and held a live performance only for distribution.

The digest video is now available on the official website. 
It was titled "Momoclo's Summer 'Baka' Fuss 2020: Hello from the 'Location of broadcast'" and was performed at Zushi Marina in Kanagawa Prefecture on August 3, 2020.

Footage of some of the songs not included in this digest can be seen at this site promoting the Blu-ray.
