This is NOT a real label.
Use this for all unofficial releases (bootlegs, counterfeits, pirate compilations) that pretend to be a release of Квадро-Диск
p.s. Please note that Квадро-Диск was one of the first Russian labels, founded in the 90s. And because of the weak copyright laws of that period it had some releases, which now can be considered unofficial or partially unofficial. Such releases should be added under Квадро-Диск label, as they do not "pretend", but were actually released by original label.
