We extend the "hard wall" gravity dual of QCD by including tensor fields bMN that correspond to the QCD quark bilinear operators q σμvq. These fields give rise to a spectrum of states which include the h1 and b1 mesons, as well as a tower of excited ω/ρ meson states. We also identify the lowest-dimension term which leads to mixing between the new ρ states and the usual tower of π mesons when chiral symmetry is broken.
