Minami talked about the rush album and that they learned about progressive rock in their institute. Hearing the word "progressive" alone sounded already difficult for her but when listening to it actually it was not that difficult to digest she said. But then the more she listened to it, the more she understood about the complexity of the musical rythmn, technique etc. Then she associated it with math at school. In her math test was also trigonometric which she didnt understand at all first and left it out until the very end. She couldnt solve it in time though. After that she tackled the problem again and remembered the basics and was able to do it on her own. The she said about "progressive rock" that is the same basically and that you have to have to know the essences that is the most important. Not only looking from the surface and think just "it is difficult" but why it is difficult.
