Hey everybody, i must tell you, i´ve purchased THE VOCALIST STUDIO - THE FOUR PILLARS OF SINGING and it´s unbelievable, it works and it´s much much much better than Singing Success, it didn´t help me, but with TVS i feel i´m getting better after every lesson i do with DVDs.. So for those who wants to SING ROCK and wants the best way how to sing better...better...best ... so i recommend TVS .. What do you think? Let´s talk about it ..
