Metallica - Kill 'em All - Released July 25, 1983

It is their debut album

Metallica wanted to the album to be called "metal up your ass" with the cover featuring a hand clutching a dagger emerging from a toilet bowl. Fortunately, Mega Force had the foresight to realize this was just a horrible horrible idea for a title and cover and were able to convince the boys that Distibutors would not stock it and vendors wouldn't sell it as it was too explicit to display.

Bassist, Cliff Burton, is credited with coming up with the title, "Kill 'em all", which was his response to the lame record distributors saying, "those record company fuckers, kill 'em all!" Lars Ulrich thought it was a good name and Megaforce went with it.  Burton suggested the cover should feature a bloodied hammer on the front.

According, to Kirk Hammett, "Cliff carried a hammer with him everywhere. he always had a hammer in his luggage and would take it out occasionally and start destroying things.

Even though the original title of, Metal up your ass was unused, Metallica later released a "metal up your ass t-shirt with the proposed artwork.  A live Bootleg recording of a 1982 performance at the Old Wardorf titled Metal up your ass (live) featuring the original artwork as well.

It has been brought up in many forum of brain-dead and drug-laden minds that the blood stain on the cover looks like a baby's head....

On the 30th anniversary of its release, Vans released a Kill 'em All shoe, which they probably wouldn't have done if it was a bloody dagger coming out of a toilet.  Not all record execs are idiots.
