The importance of exploring genres
There are so many reasons why singers should expand on genre experience. It builds confidence, technical skills, stylistic skills, and performance skills. If singing is a career move for you, the more genres you cover, the better chance you have of expanding your repertoire, making you more versatile to potential employers and/or bands. It's not about being able to sing every genre under the sun, but at least having 2-3 genres you can store under your belt.
