Sorry for coming back! Your cover is so good! This is my favorite iDOLM@STER song. I love progressive rock with my whole heart and I truly believe this song is a wonderful tribute to the genre. Really found interesting and adorable, and it makes me feel incredibly emotional. It's a big, beautiful tribute to prog rock and its origin (and also a nod to the era the genre got "founded", which is 1969). By the way, what do you consider it influenced this song? Like the bands that inspired it. I talked with another imasP and he told me there are some Camel influences in Reimei Starline.
I thought it's in 4/4(&2/4) throughout. But, 1:26 2:40 may be in 5/8 + 7/8! I recommend you "re:frution" composed by Yamamoto Maoki, the composer of this song. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-AVPK8rWMxGQ.html
