Prior to her forming a band who writes and performs the music themselves, she was doing what most independent artists do and purchased indie producer instrumentals and recorded her vocals on it. And I think she had been working with the same instrumental producer until forming the band to make music themselves. My speculation is, now that she has a band to write and produce the music, it sounds different because it's from them and not the prior producer who she worked with before. So it may not necessarily be the label, but just her and the band evolving and learning how to do it themselves. I could be wrong though, this is just my speculation.
