Sigil Of Brass
~ Audio Mastering studio, Harrogate.
I built a website for a music mastering service.
Sigil Of Brass rent out a room at Creao Studio and have ties with Guerrilla Dub System. They master all of the music for Focused Silence and are reasonably priced. If you want to see about getting your music mastered at a competitive rate, please see the link below.
