At the end of June, Metallica announced via Universal Music they would re-release "Enter Sandman" for the 30th anniversary of the band's legendary self-titled album, otherwise known as The Black Album. According to a report from Germany's Big FM, the profits from the re-release are going to a benefit effort set up to help victims of the floods that have plagued Germany in recent weeks. This is being done through Metallica's All With My Hands charity organization

The official statement (translated) is available below.

"All the profits of the German-exclusive physical single "Enter Sandman" (Remastered), which was released on Friday 20.08., will be donated by Metallica through their foundation All Within My Hands to the victims of the flood disaster that shocked all of Germany and the world a few weeks ago. The single was already planned months ago as a charity release for various projects, but the disaster immediately made Metallica active, so that the profits in this country, as a sign of the solidarity of the band with those affected, should be used."

"Enter Sandman" (Remastered) is currently heading to #1 on the German charts according to mid-week rankings released on Wednesday, August 25th.

"Germany! 'Enter Sandman' (Remastered) is available as a limited edition, numbered, glow-in-the-dark 7" Vinyl single as well as a Maxi CD and 3" PockIt CD single, both of which include previously unreleased live tracks recorded in Germany in 1992. Pre-order here."
