Metalheadz Sunday Sessions
Like Ben UFO, I've never been to the Metalheadz Sunday Sessions at London's Blue Note club, which took place between 1995 and 1998. In my case, it's rather bitter realizing I bought the first Platinum Breakz compilation whilst in London back in the summer of '96, so I actually had a fair chance and blew it.
Anyway, Metalheadz uploaded a VHS rip documenting those days to their YouTube channel, “featuring a whole heap of familiar faces and a DJ Set from Grooverider”, not to mention the fancy 3D renderings. On top of that, make sure to check out several recordings from the Blue Note on the Metalheadz SoundCloud page.
