Also appeared as "Music-Hall", "Discos Music-Hall" and uses the logographic motto "MH ..es Argentina!".

Argentinian label, owned and distributed by SICAMERICANA S.A.C.I.F.I. (Sicamericana Sacifi).
Originally typographed as Music-Hall in the 50s, it dropped the dash on the logo by the end of the decade. From the 50s to the late 60s it mostly released licensed recordings, with inclusion of beat and tango. From there onto the late 80's, most of the releases were from Argentine artists. The end of it's tenure were mostly compilations (VA) of European artists.
Went bankrupt in the 90s and the masters were shelved until the late 2010s. In this period, a large number of unlicensed and bootleg reissues were made.

Music Hall catalog # works the following way:

The first number defines the type of release - The other four numbers define the cat.

X.XXX - LPs produced from artists signed with the label
1X.XXX - LPs not signed with the label or artist not directed associated with Music Hall.
3X.XXX - Singles
6X.XXX - EPs
7X.XXX - Compilations & Anthologies
9X.XXX - LP Reissues.
11X.XXX - Stereo - Available when an LP had Mono and Stereo versions on sale
50-XX.XXX - Licensed, adopted for all released on a short time between circa 75 to circa 78. May also come in 60, 70 or 80

Do not add MH- to the catalog. That's part of the matrix's side identifier. The dot separating most cats was added circa the 2000th national release.
