ストロベリーソングオーケストラ (Strawberry Song Orchestra) are releasing 2 new digital singles on 2021/08/06 (already available due to timezone differences, heh).
I assume they’ll be up on Spotify, Youtube and all the usual digital platforms soon enough. For now, I found them on OTOTOY:
Also worth mentioning here in case anyone missed it, they’ve already released 2 other one-track digital singles earlier this year, namely あなたの匣に眠りたい and 暗ビリカル記号ジャメヴ.
