Hello I am a vocalist in a Rock band called Joyous Wolf I have been singing in the band for about a year now and we've received many accolades in our short life time as a band. I am inquiring because I am experiencing some vocal fatigue. After our sets which can range from 30 minutes to an hour I am fine while on stage, and I don't feel any strain. But once I go to bed the same night and wake up the next morning I am in pretty rough shape. The style I sing in is shown in the live video below. Please lend me a hand.
