For me, one of the important things about keeping vocally healthy is warming up and making sure I'm aware where my voice is at, drinking lots of water and getting plenty of sleep, and just taking care of myself with exercise and eating healthy.
There are female artists I can look at that I find more in common with than the male artists, because they're blending the pop, dance and theatricality... but currently there aren't a lot of guys who go there.
Bowie's been a huge influence on me. I remember early on, my dad pulling out the 'Diamond Dogs' album, and the cover alone just grabbed my attention. I think I was probably around 12.
