This comes from some of the unused footage for the Hammer To Fall promo, which was shot at the Forest National in Brussels on August 24th.
Most of the promo would be shot on the following day during the soundcheck.
Notable footage shot are Somebody To Love and Under Pressure (as identified by someone).
There was once someone who did a compilation of the Brussels *live concert* footage but the video has disappeared somehow.
An audience amateur footage also exists, capturing at least five songs according to .
