It's time for another giveaway, and this time you'll wanna break out the blacklight -- we're giving away a trio of Pink Floyd-related prizes to celebrate the recent release of The Dark Side of the Moon's 40th anniversary edition! One of the most commercially and critically acclaimed albums of all time, The Dark Side of the Moon was Pink Floyd's first to reach number one in the U.S., where it remained for a whopping 741 weeks through 1988 (in its native UK, the album has spent three decades on the album charts).

In addition to its sonic singularity, which AllMusic's Stephen Thomas Erlewine describes as "subtly textured music, which evolves from ponderous, neo-psychedelic art rock to jazz fusion and blues-rock before turning back to psychedelia", the album showcases the artwork of recently departed iconic graphic designer Storm Thorgerson, who created 14 new prism designs, unveiled on PinkFloyd.com to form a commemorative poster.
