I'm constantly searching for danceable music without drum machines for my DJ sets in clubs or festivals which work well alongside modern dance music production. 
It's a particularly beneficial practice to break down what makes them so functionally danceable for my own production work, from the instrumentation to the arrangement and sonics. 
For this mix I've gone through my record collection and compiled a selection of standouts that resonate with me in this way and tried to include varying genres rather than an all disco mix. 

It's mixed live so there are drifting imperfections included.
