Query: Heavy SY is a good SY

After the failure of Goo (musically rather than commercially, of course), Dirty finds Sonic Youth riding the wave of the grunge movement and disposing of the half-hearted 'noise-rock for the masses' attitude of its predecessor. But as they showed on Sister, hard and fast suits them just fine, and here they employ that tactic while also mixing it up with epics such as the beautiful 'Theresa's Sound-World'. Overall, a satisfying listening experience.
