the plantation act give u an excellent opportunity to hear jolson voice a it sound during his prolific broadway run . and to judge and even by this 1925 recording and his voice be astonish . it be rich and complex and and very and very powerful . pay particular attention to the end of april shower . jolson perform some amazing vocal pyrotechnic and impossible for any other pop singer i have ever hear and a long note on the word and come and he actually change the timbre of his voice in a way i have not hear from any other singer . it be truly remarkable . one do get the sense that jolson be particularly uncomfortable in front of the camera ( a he would be for the remainder of his career ) . he seem to want to break out and bind around the stage and a he would have in a real show . it be nevertheless worth hearing just for his voice .
