Time correlation functions of a hybrid exotic meson operator, with J{sup PC}=1{sup -+}, generated in quenched lattice QCD are subjected to a (Bayesian) maximum entropy analysis. Five distinct spectral levels are uncovered. Their extrapolation into the physical pion mass region suggests a possible relationship to experimentally known states {pi}{sub 1}(1400) and {pi}{sub 1}(1600), and also to a state in the 2 GeV region carrying the same quantum numbers.
