Cazqui's Brutal Orchestra is an active visual kei solo project. They are part of the loud kei subgenre. They have been active since around 2019.
I am thinking there was, I was going to update the lineup as there is a violinist in the new music video they put out, but I was unsure if he was in the band or he was supporting or was even in the band at all. As there was no info I can find about the violinist being in the band.
