I think it' quite a recent series. Starts with four girls in an air band, as in playing music and pretending tp play instruments like the air guitar.
 Any idea what this is?

Are these the girls?

Thanks for replying but I don't think this is it. By air band they don't have the physical instruments. Music plays while they do the movements as if they were playing instruments, but are holding nothing.

I've trawled through literally hundreds of music anime descriptions going back to 2021 and come up with a bust. Sorry.

Any idea as to the studio, a voice actor?

Thanks for helping, I managed to find it. Maesetsu! Opening Act

Ah! It's from 2020. I didn't go back far enough, and I was probably searching for the wrong genre as the MAL description doesn't mention music at all.

Well done for finding it.
