  High red-shift radio galaxies are best searched at low radio frequencies, due
to its steep radio spectra. Here we present preliminary results from our
programme to search for high red-shift radio galaxies to ~ 10 to 100 times
fainter than the known population till date. We have extracted ultra-steep
spectrum (USS) samples from deep 150 MHz Giant Meter-wave Radio Telescope
(GMRT) observations from one of the three well-studied DEEP2 fields to this
affect. From correlating these radio sources w.r.t to the high-frequency
catalogues such as VLA, FIRST, and NVSS at 1.4 GHz, we find ~ 100 steep
spectrum (spectral index, $\alpha$ $>$ 1) radio sources, which are good
candidates for high red-shift radio galaxies.
