Dan It’s all a of load of shit.
Old School Techno 140bpm
Modern Day Techno 130bpm
That’s literally bullshit.
The problem is most of you on here listen to what the likes of Digweed, Tale of Us, Adam Beyer etc. are peddling while calling it “techno” while really it’s middling tech-house.
Meanwhile there are loooads of big DJs and producers out there still pushing 140bpm+; in fact high bpm techno from 140 even up to 155bpm has had something of a mini-renaissance in the last few years.
