### Description

We explore the detailed structure of the {\em ridge} in the Color-Glass-Condensate (CGC) effective field theory of QCD and demonstrate a novel mechanism that produces a non-vanishing $v_3$ without final-state re-scattering. A $v_3$ in agreement with the LHC p+Pb data is generated by the interference of diagrams attributed to the jet (away-side) and ridge (near-side) substructure of the azimuthal correlation. We also find that the $v_3$ in p+A is comparable to that in A+A for similar multiplicities.
