(MUSIC) One of the hardest things to do in music is to make quiet rock compelling. Most bands of this ilk come off as meek whiners with feeble chops. However, you can count the Clientele as masters of this style. Their music engenders a sublime intimacy, a hushed splendor; imagine Galaxie 500 tackling the mellower tunes off Love's Forever Changes. Yes, that amazing. The Clientele prove that few things are sweeter than capturing romantic ache in song. (Chop Suey, 1325 E Madison St, 324-8000. 9 pm, $10 adv, 21+.)
