Frozen Starfall is a German doujin music circle that was founded in 2015. Their lyrics are mostly in German (translations of some at the bottom of the page!), with instances of English and Japanese lyrics.
The circle has collaborated with several notable artists in the Touhou doujin music community. They produce physical albums that are released at comiket, but all of their albums are also available for pay what you want download from Bandcamp.
Their Bandcamp page describes their style as mainly electronic music such as House and Techno, with occasional exploration of other genres. Their lyrics deal with many facets of life and are not afraid to delve into complicated emotions, but range from carefree to reflective.
