Luminous Red Galaxies (LRGs), dominating the most massive tail of the galaxy population, are traditionally considered to have had a simple and mostly passive evolution. Crucially, this assumption has a wide-ranging impact - from galaxy formation to large-scale structure surveys. The evolution of LRGs must be described not only in terms of star formation, but also in dynamical terms. I will present a comprehensive study of the evolution of LRGs, show how a novel clustering analysis and new sample selection techniques have given us new insight on the dynamical evolution of these galaxies, and discuss how even in the simplest case galaxy evolution is still very hard to solve.
