Musician have poor memory. If you go to classic orchestral concert, you notice that all orchestral members cannot play without score. Even cymbal player who klap it only few times seem not to be able to memorise score. I cannot understand why classic orchestral musician cannot memorise their score nev er the less their music have been played million times from classic era. They must be realy poor memory. But they are still great because they actually play instrument and sing. Modern musician cannot play nor sing. They just move their mouth rhythmically in accordance with pre-recorded tape. The reason Mich el Jackson, Madona, Britony keeping to move around stage with sexual costume is that they try to get audience attention except their mouth by audience. In such situation, what can we hope to street musician ? I nev er blame this person for his poor memory. I nev er condemn this person for his poor technique. But I wis h this person have strong vision as a musician. No need memory, nor technique, but strong vision. Very strong vision in stead of sunglass. if you Click the “READ MORE” link ! and see the last picture, you will understand what I want to say. He maybe cannot play without score. and he also maybe cannot play without strong vision.
