Usually, at least on this forum when someone speaks of "offbeat" techno it deals with stuff like Olga & Josef, Rumengie, Lokitbrada, Wunsch and all that other stuff.
It seems as though this is the new popular stuff for people who like the darker, harder side of techno (some people get tired of compressed heroes techno I guess). I'm totally into it but the hype around it is pretty overrated. 95% of the records to come out from the majors of this stable are the same formula: 3 minute drum track, all drums, really repetitive, and some dark pad progression made in 5 minutes to be the main hook of the track (which doesn't really make it memorable at all). Not to say other styles don't use certain formulas (they all do) but lately all these new artists that are spoken of on the board are putting out the same rehashed stuff.
More on topic...its funny how they call it off beat techno because there actually is a beat. The name just comes from the kick drum being placed on notes that aren't on the "four to the floor" beat that techno has used as a standard.
