I personally like the idol band AKB48 and have listened to most of their concerts and been too the official theater in Akiba. I wasn’t sure what is was when I went and I actually didn’t start really listening to them till a few years after my trip to Japan. However, after seeing LoveLive! and a few other idol anime, I usually gravitate to the original stage concert’s I found on YouTube and such… so since I have a desire to learn piano better, I started finding some random videos of people who are really great at piano and play AKB48 songs. This is a great way to keep focused on being creative and productive in my life, so I hope you are inspired to learn an instrument or simply enjoy someone else’s playing.
