  We set up the Sugawara-Sommerfield (SS) construction and generalize it by the
inclusion of canonical spin current. Using the techniques of current algebra,
we infer that the canonical spin current are linear in the vector-axial vector
currents. From a geometric perspective, the underlying manifold has a vanishing
Lorentz curvature and a non-vanishing torsion. This leads to teleparallelism
and the canonical spin current (connection) assume a pure gauge form. Moreover,
this model provides a possibility to unify gravity with strong-interactions by
expressing the gravitational gauge connections in terms of the Yang-Mills gauge
connections.
