Set craft
Emergency track
An emergency track is a record you keep for when a set is going wrong — something that has never failed in that kind of room, kept somewhere you can find it in five seconds without browsing.
In practice
Chosen in advance, findable in five seconds. The moment you need it is the moment you cannot think.
Keep three or four in a crate of their own at the top of the list, and put genuinely different things in it — something that rebuilds slowly, something that lands immediately, something for the case where the room has gone quiet rather than left. Use them and replace them: a rescue record you have played at that venue three times is no longer a rescue. And practise finding the crate blind, because that is the actual skill.

Where these come from: Set-recovery practice, not a catalog figure. For what we can measure, see the situation it answers.
Why it matters
It exists because the moment you need it is the moment you cannot think. A floor that has thinned, a transition that landed badly, a technical problem that lost the room — all of those produce a few minutes where your judgement is worse than usual, and a decision made in advance is better than one made then.
It is also the argument for a crate that is not organised by genre. Whatever you keep for this has to be reachable in one press, and a folder called "peak" that you can find blind is worth more than a perfect taxonomy you have to read.
Frequently asked
What makes a good emergency track?+
One that has never failed in that kind of room, and one you can reach in seconds. Reliability matters more than quality here, because you are not trying to impress anyone at that moment.
How many should I carry?+
Three or four, and genuinely different from each other — a slow rebuild, an immediate hit, and something for a room that has gone quiet rather than empty.
Where should I keep them?+
In their own crate at the top of the list, findable without reading. Browsing is exactly what you cannot do when you need one.

Clearing the floor
Clearing the floor is emptying a dancefloor with a bad choice or a bad transition. It happens to everyone, and what separates DJs is how long it takes them to notice and what they do next.
Floor filler
A floor filler is a record that reliably brings people to the dancefloor. It is defined by what it does in a room rather than by anything in the music, so it is one venue’s and not another’s.
Crate
A crate is a folder of tracks inside your DJ software, named after the boxes vinyl DJs carried. A track can sit in as many crates as you like without being copied, because a crate holds references rather than files.
Set prep
Set prep is everything done before the gig — choosing candidate records, checking cues and grids, building crates, and exporting a stick. It is preparation for decisions rather than a script for them.
