Speaking of singing, do you know about “The Zen of Screaming”? It’s an excellent DVD package of singing instruction, voice toning exercises, and downhome advice on how to belt out big musical numbers more effectively created by classically-trained singer Melissa Cross, who has coached many singers, speakers, and punk rock screamers on how to use the voice properly. If you get that achy catch in your throat when you sing in religious services, you’re either not singing enough, or you might benefit from a few of Cross’s singing tips. Here’s a delightful video clip of her on Conan O’Brian’s show.
