This paper summarizes some of the ongoing projects on the CORALZ sample, the first statistically complete sample of young radio galaxies. The low redshift of the sources in the sample ({z <0.16}) makes them excellent targets for a comprehensive and homogeneous follow-up in virtually all bands of the electromagnetic spectrum. Here we report on the almost completed radio continuum observations which confirm the relatively young ages of the sources in the CORALZ sample. The radio spectra in addition with new measurements at 250 GHz indicate a large fraction of sources with excess mm-emission, probably due to radiation of cold dust. These sources are also excellent candidates for detection of molecular gas, which we have traced through CO observations in the 3-mm band in several cases. Additional molecules as H_2O or OH are being observed. The atomic gas content is disclosed by H I absorption observations.
