In terms of taking care of my voice I try to drink lots of water and stay really hydrated. I don't smoke, I never drink any alcohol or coffee before a gig. And I try to get enough sleep on the road, a really important thing and sometimes a very difficult thing to do. Let's talk about the state of country radio. There was a time when you could hear hillbilly, bluegrass, western swing and other forms of traditional music on country radio.
Less emphasis is placed on the music and more on the slick image and youth.
Stations have gotten much more narrowly formatted. But, that's all beside the point. They would play soul music, country music, bluegrass, jazz, anything they wanted to play. The DJs had complete free reign and it was an extremely popular station. I personally like being surprised.
