Investigating $LaN_{2-x}M_xO_3$ (M ­ Mn and Fe), we identify a characteristic evolution of the spectral function with increasing disorder in the presence of strong interaction effects across the metal-insulator transition. We discuss these results vis-à-vis existing theories of electronic structure in the simultaneous presence of disorder and interaction.
