Wondering when mixing vinyl and you are transitioning from a House track to a more electro track then to a Techno Track. What does through your head as a DJ when the second track is slower or faster but also has a different flow to it. Also do all DJ mix in the same key? Does it sound bad if you dont? Is it worth taking the risk? I see people like Derrick May that perfectly delivers the contrast of going from House flow to Techno to Tribal House to Electro and im amazed by the contrast and the perfection of seamless transition to each track. Making it seem like there all the connected.
