  Searches for new hadronic resonances typically focus on high-mass spectra,
due to overwhelming QCD backgrounds and detector trigger rates. We present a
study of searches for relatively low-mass hadronic resonances at the LHC in the
case that the resonance is boosted by recoiling against a well-measured
high-$p_{\textrm{T}}$ probe such as a muon, photon or jet. The hadronic decay
of the resonance is then reconstructed either as a single large-radius jet or
as a resolved pair of standard narrow-radius jets, balanced in transverse
momentum to the probe. We show that the existing 2015 LHC dataset of $pp$
collisions with $\int\mathcal{L}dt = 4\ \mathrm{fb}^{-1}$ should already have
powerful sensitivity to a generic $Z'$ model which couples only to quarks, for
$Z'$ masses ranging from 20-500 GeV/c$^2$.
