  A light pseudo-scalar that is copiously produced at the LHC may still be
allowed by present searches. While masses above 65 GeV are effectively covered
by di-photon searches, the lower mass window can be tested by a new search for
boosted di-tau resonances. We test this strategy on a set of composite Higgs
models with top partial compositeness, where most models can be probed with an
integrated luminosity below 300 fb$^{-1}$.
