You're welcome! As for 新宿ゲバルト, they're a duo that only works when Toda and Shimizu have the time to work together so their release schedule is sporadic. That being said, they still work together, even in 2020. They even released a mini-album a few months ago. Their newer stuff is often live distributed/mail order only so it's very hard to find it online, however. They were still doing live performances too, prior to COVID-19, but that's obviously changed.
