Unknown (HB)

This profile is used to link the anonymous manufacturer of CDs, which can be identified by CD matrices 'HB xxx', where xxx are 3 digits (for example, HB 404).
Unofficial sources say this manufacturer had a connection with SHUM Records and can be referred to as a 'pirate department' of the label. This is proved by the following facts:
- some of SHUM Records releases come with matrices of the same pattern
- the styles of music, released by this company, are similar to SHUM Records
- Nevertheless all releases Unknown (HB) are considered official.

'HB' CDs were originally sold in Russia and neighbouring countries.
