“On the momentous occasion of its eight-year anniversary, how does one even begin to honor a piece of pop history as great as BLACKOUT? Much has been written about the iconic LP, released in 2007 as @britneyspears‘s fifth studio album, but its legacy is clear: BLACKOUT predicted the dance invasion of the last several years and the importation of dubstep (with a wobbler effect used prominently on the album track “Freakshow” well before Brit co-opted the explosive dubstep break in “Hold It Against Me”) while refining the formula for coolly sexy, tortured pop. It’s probably Spears’s greatest artistic achievement, and one of the top pop albums of the decade.”
