  We report the first results of the MUSIC project. It consists of two data
sets of resimulates clusters extracted from two large dark matter only
simulations: Marenostrum Universe and Multidark. In total, the MUSIC contains
more than 400 clusters resimulated with high resolution both with radiative and
non-radiative physics included. Here we present the first results on the
properties of the baryon content and the Sunyaev Zeldovich scaling relations.
