  We construct a novel supergravity background holographically dual to the
flavoured N=1 Supersymmetric Yang-Mills theory. We consider flavours of
different masses that produce spherical cavities with radii corresponding to
the quark masses. The positive beta function blows at some large radial
distance corresponding to the Landau pole of the theory. We explore the Wilson
loop between two families of light and heavy quarks and observe a screening of
the heavy light potential.
