  We discuss a class of vertex operator algebras $\mathcal{W}_{m|n\times
\infty}$ generated by a super-matrix of fields for each integral spin
$1,2,3,\dots$. The algebras admit a large family of truncations that are in
correspondence with holomorphic functions on the Calabi-Yau singularity given
by solutions to $xy=z^mw^n$. We propose a free-field realization of such
truncations generalizing the Miura transformation for $\mathcal{W}_N$ algebras.
Relations in the ring of holomorphic functions lead to bosonization-like
relations between different free-field realizations. The discussion provides a
concrete example of a non-trivial interplay between vertex operator algebras,
algebraic geometry and gauge theory.
