With thanks to Slim Forsythe. Sound check -- a mundane essential for any artist, any performer. Testing – one two, three... Testing – one two, three... Can you hear me in the back? A little more on the right mike, please. How's the lower registers? No, you shouldn't hear any hum. Now, check the drums: kick, tom, snare, top hat, cymbals. Now we'll check the whole kit. A little more vocal on the drum monitor, please. Testing – two, three, four... Check -- four, five, six. Thanks, we're ready. This, too, is a craft and as an art. It's a job nobody notices if it's done right. So the wise performer always thanks the sound crew.
