Carole & Tuesday, Kono Oto Tomare! Recommendations
Both anime feature characters who are trying to prove themselves and overcome their trials and tribulations. While one is set in a futuristic sci-fi setting and the other is in a current day Japan school life, music is what really ties them together. You will watch full and soothing performances (plus some EDM inspired music in Carole & Tuesday) with acoustic instruments (koto and guitar/piano) in both anime which can also be incredibly inspiring. Overall, both shows are very wholesome.
both of them base on music and fighting on the stage to be top
they both trying there best wile they are nervous but still do there best
but there back ground story is completely opposite but still there is some one supporting them
