We continue the investigation of large $N$ QCD from a modern bootstrapperspective, focusing on the mesons. We make the natural spectral assumptionthat the $2 \to 2$ pion amplitude must contain, above the spin-one rho meson, amassive resonance of spin two. By maximizing its coupling we find a veryinteresting extremal solution of the dual bootstrap problem, which appears tocontain at least a full Regge trajectory. Its low-lying states are in uncannyquantitative agreement with the meson masses in the real world.
