XS in Frankfurt and The Milk! Club in Mannheim are considered the germinating places for Breakbeat Hardcore and later Jungle in Germany. (There were smaller crews in Berlin, Cologne and Hamburg). Bryan G was playing in 1992 at Milk!. Marc Spoon and Alex Azary were involved in the XS and they offered the Milk! crew to play at XS and they all dove back and forth from 1992 - 1993. It's not that far, only an hour by bus.
I know that there are a few recordings from XS and Milk! but i think most of them would've been uploaded already by Shar-Pei if they were plentiful. So good luck finding more. I've seen some smaller snippets on Soundcloud where people wanted ID's from unknown sets, but i'm not sure if they took it from their personal tapes or from mistagged sets on the internet.
Names to look for Sets from 1992-1994 are: Bassface Sascha, Groover Klein, DJ Tobi & Jonathan, Bleed & Triple R (with a stronger focus on Breakcore), E.Decay, X-Plorer, Numinus (Cologne/Köln), Jan Sirup, Shar-Pei (He posts a lot of Milk sets! https://www.mixcloud.com/Dj_Shar_Pei/) , Bassline Generation, Oliver von Felbert/Dagmar Da Mörderin (Cologne/Köln), State of Riot Crew in Munich.
A huge Event from 1993 was Euphoria at Dorian Gray in Frankfurt in May.
NTT was the main distributor of Breaks and Jungle from early as 1992.
