In particular, in new strongly interacting sectors they play the role of the $\\rho$ and $\\pi$ mesons in QCD. We show that some of their interactions, for example those required for the explanation of the $B$ anomalies and the $g-2$ of the muon, can be only probed in $B$ meson decays. We highlight new golden channels not yet studied experimentally, including $B^+ \\rightarrow K^+(D^+)\\mu^+\\mu^-\\mu^+\\mu^-$ and $B^0\\rightarrow K^{*0}\\mu^+\\mu^-\\mu^+\\mu^-$.
