Honestly, especially after seeing Brandy live on Broadway and hearing the favorable comments from the young and older audiences in the crowd, I think Brandy focusing on ACTING will only extend her career and give it an ever-lasting effect. It crosses all formats (demographics) on Broadway. I was in awe by the raves I was hearing behind me, next to me, etc.
I wouldn't mind Brandy really challenging herself in roles and really dominating acting in her 40s.
I know she has the voice for a lifetime of singing. And she will release her albums whenever she feels likes it - and the response will be based upon her team.
But acting is what is going to keep this woman around for decades.
Some people do tours (Tina Turner, Beyonce, etc).
For Bran, it'll be acting.
