Heather Headley Instagram – My voice is a giving a little attitude, so I’m in athletic mode…two-a-days (at least). So, here’s the second warm up of the day, because next #Sunday… It’s #Chicago. It’s #Ravinia It’s the @chicagosymphony With @marinalsop.conductor And a surprise guest I invited, who I can’t wait to share the stage with, and who told me to #strapin because we are getting ready to #SING!! So, I’m #warmingup! #happysunday
