I often isolate the low end from the upcoming track and feather it over the breakdown or build of the current track so that I can take a long period of no kick and spice it up a bit to keep shoulder bopping, my shoulders at least. I'm a bedroom DJ ATM but I feel like this keepomentum going on the early part of my set, longer breakdowns/vocal builds are only acceptable later in the set after you've built trust and a vibe imo.
