  We calculate the redshift-space power spectrum of the Sloan Digital Sky
Survey (SDSS) Data Release 4 (DR4) Luminous Red Galaxy (LRG) sample, finding
evidence for a full series of acoustic features down to the scales of \sim 0.2
hMpc^{-1}. This corresponds up to the 7th peak in the CMB angular power
spectrum. The acoustic scale derived, (105.4 \pm 2.3) h^{-1}Mpc, agrees very
well with the ``concordance'' model prediction and also with the one determined
via the analysis of the spatial two-point correlation function by Eisenstein et
al. (2005). The models with baryonic features are favored by 3.3 \sigma over
their ``smoothed-out'' counterparts without any oscillatory behavior.
