It is with great sadness that we announce to our fans and family the passing of our elder and singer Ras Jahn Bullock. He had been battling liver cancer for some time and seemed to be doing ok for a bit, but things took a turn for the worst last night. That being said, he passed away peacefully in the presence of his wife and a few family members. Ras Jahn will never be forgotten, he had a mystique about him like that of a Rasta super hero within a comic book story, equipped with his staff and surrounded by ganja smoke. Humble and gracious while at the same time serious and about his business of making music. Ras joined The Alchemystics at the end of 2006 and brought a great knowledge of reggae and old school soul to the table. One of his distinguishing musical characteristics was his amazing falsetto harmonies and his remarkable ability to layer them in the studio with the effect of a soul choir. We will cherish his memory forever in our hearts and feel his guidance and spirit in the music he left with us. Jah Love!
