Releasing the monthly Hammerworld Magazine, they were also Hungary's only major metal label.
The label changed name to H-Music (Hangfelvételkiadó Kft.) to become a different legal entity to the magazine.
All CDs are first released with Hammerworld magazine, as a disc in a plastic sleeve. The disc tray and a basic 4-page booklet are included in the magazine, printed on a simple page, with scissor marks for those who wish to house it in a jewel case.
Then there is a second version, either digipak or jewel, with full booklet, that is sold in the shops. The disc itself is the same as in the aforementioned version.
