For days, I've had the first 10 seconds of Brick's "Dazz" on a recurring loop in my mind. I have no idea what triggered it, but that instrumental intro seems to be lodged in my mind for good. The tune, whose title stands for "Disco Jazz," was a big hit in late 1976 and early '77. If its title doesn't ring a bell, seek it out. Chances are, you've heard at least the first 10 seconds of it on an oldies station or sampled in a DJ's mix at a party.
