Omoide Hatoba started off in the dark slow and quietly, and slowly increased in tempo. Eventually Yamamoto Seiichi (also know for his guitar playing in the Boredoms) walked onto stage, and things got very intense. After about 20 minutes the band left the stage, but were brought back by 5 solid minutes of applause from the crowd. I wish I could figure out a better way to describe the event, aside from counting the guitars samplers keyboards drums and vocals. I thoroughly enjoyed it.
