After six months of practice , in 2012 Tank came back to the stage with a new approach to the script . The main reason behind this alteration was the director's return after 7 years . Since the Tank in 2012 , Jalal Tehrani has gradually distanced himself from stirring up the audience's emotions and hence the second Tank is no more an emotional melodrama . By means of introducing all hidden characters to the stage and creating anti - sentimental passages with escal their help and Alireza Mashayekhi's music , the director succeeds in creating of the te W a broad range of distancing effects . Almost all of the spectators who have watched both performances of Tank within the span of ten years find the first the fact that performance more thrilling , which refers to the fact that the performance has avoided unbridled sentimentalism even if being performed with the same crew as the first performance . The outstanding point of the second performance of Tank is Alireza Mashayekhi's presence as composer . Based on a report from the public relations section of Molavi hall in 2012 , this play is the most largely attended performance in this hall's history since its opening in the 70s .
