J Blood Supreme is a female Texas rapper and producer who gained recognition and respect with her first mixtape title 'Unleashed & Underestimated' 2010 under the stage name SinCere. She was most definitely unleashed and totally underestimated, gaining the attention from Texas, Louisiana, Mississippi, and Illinois and gaining respect from well known promoters, local radio stations, and well known independent record labels. J Blood Supreme is currently working on her next self-titled mixtape/album. She is going strong and refusing to go home and from the looks of it we can plan to see more of her as she reaches for the top. With heart, a powerful deliverance, strategy and skill, this emcee is headed towards all she has imagined plus more, she is truly... on fire.
