After I get a massage, my voice drops several whole-steps lower! I'm a tenor 1, but after a massage, I can make it all the way down to a C1 with really loud chest-resonance.
Rule of thumb for East Village massage places, the worse the decor, the better the massage. Tiger AND Leopard sheer-curtains means you're in for the massage of a lifetime!
...a thing called a Thera Cane
that allows you to get at hard to reach muscle-knots on your back. (While I'll still occasionally use this and it's awesome, I know pretty much recommend buying a lacrosse ball and using it to roll against a wall. Much easier!)
I'm alway asking Meredith to walk or kneel on muscle knots in my back and over the years she's gotten real good at it. Ellen had a sore mid-back and so Mer went to work.
