We present the 2D angular power-spectrum of the Luminous Red Galaxies (LRGs) selected from SDSS III - DR8 data release. It consists of 12,000 sq deg, more than 1.5 million LRGs, making it the largest volume ever used for a galaxy clustering measurement. These LRGs have accurate photometric redshifts, enabling us to reconstruct the 3D power-spectrum from their angular power-spectrum. We present initial cosmological constraints from these data.
