Roots of Bathory

Hellhammer was a Swiss extreme metal band from Nürensdorf, active from 1982 to 1984. Although the band's sound and style were heavily criticized and poorly reviewed during their active years, they have been widely praised in retrospect and are often regarded as a key influence on black metal. In June 1984, Hellhammer disbanded but two of its members soon formed the influential extreme metal band Celtic Frost.

Paul Daniel "Ace" Frehley was an American musician who was the original lead guitarist, and occasional vocalist, and a founding member of the rock band Kiss. He invented the persona of the Spaceman and originally played with the group from its inception in 1973 until his departure in 1982, before later rejoining in 1996 until his final departure in 2002.

Kiss was an American rock band formed in New York City in 1973 by Paul Stanley, Gene Simmons, Ace Frehley and Peter Criss. Known for their face paint and stage outfits, the group rose to prominence in the mid-1970s with shock rock–style live performances that featured fire-breathing, blood-spitting, smoking guitars, shooting rockets, levitating drum kits and pyrotechnics. The band went through several lineup changes, starting with drummer Eric Carr replacing original drummer Peter Criss in 1980, with Stanley and Simmons remaining the only consistent members. The final lineup consisted of Stanley, Simmons, Tommy Thayer and Eric Singer.

"I'm Only Sleeping" is a song by the English rock band the Beatles from their 1966 studio album Revolver. In the United States and Canada, it was one of the three tracks that Capitol Records cut from the album and instead included on Yesterday and Today, released two months before Revolver. Credited as a Lennon–McCartney song, it was written primarily by John Lennon. The track includes a backwards lead guitar part played by George Harrison, the first time such a technique was used on a pop recording.

Black Mark Production is an independent record label originally based in Berlin, later on with offices in Stockholm, Toronto and New York City.
