Surprisingly, the majority of massive galaxies at z~2 are detected in deep Spitzer 24 micron observations, implying that these galaxies experience intense IR activity at these redshifts due to obscured star formation or AGN. However, our interpretation of these galaxies' IR emission is compromised because we have only photometric redshift (z_ph) estimates for the vast majority of these galaxies, which translates to large uncertainties in converting the 24 micron flux densities to total IR luminosities - we are simply too redshift starved. We propose to use Keck/LRIS to measure redshifts of ~100 massive galaxies detected at 24 micron (and another ~100 galaxies undetected at 24 micron) with 1.5
