BMI Creatives team weighs in on this important question. Here is what they had to say:
MaryAnn Kee.Creative, Nashville (Country)n believes vocals and production are equally important. A producer must create a song that has to be good enough for the artist want to express it as their own words to get the most desirable vocals.
Omar Grant, New York (R&B/Hip-Hop) believes production is the most important of a demo because production creates the final track from start to finish. He says that the only time vocals are important in creating a demo is when the vocal track is being recorded but fine tuning vocals is a part of production.
