We propose that $O(10 M_{rm Sun})$ black holes observed by LIGO/Virgo
originate from a first order QCD phase transition at a temperature $T_*
lesssim 100$ MeV. This is implemented by keeping the Higgs vacuum expectation
value and hence quark masses at zero down to $Tsim T_*$, making QCD
confinement a first order electroweak phase transition. This electro-strong
transition could have interesting ramifications for particle cosmology, as
electroweak sphalerons stay active till $T gtrsim T_*$. We realize our
scenario through hidden gauge dynamics and a scalar which could potentially be
viable dark matter.
