B2B means back to back. Two DJs, one mixer, often one deck each. They hand tracks to each other. Good when they listen. Bad when they drown each other.
A B2B set is not a battle and not a shared playlist. It is a conversation on the decks: one plays, the other answers, the floor hears whether they build the same room.
Flyers write “Name B2B Name”. Three or four DJs on one mixer still get called B2B, even when the label stretches.
