In 2009, band members Brian Molko and Stefan Olsdal began to publicly state that they were working on material for another studio album. On 23 November 2011, the band announced via their Facebook page and official website that they would return to the studio in 2012 to record their seventh studio album. Placebo confirmed in late May 2012 that they expect to release some tracks by the end of year, and that they have been assisted by Adam Noble (Red Hot Chili Peppers, dEUS) on a new album which will be released by the Northern Hemisphere summer in 2013. In August 2012, Molko revealed on Italy's Rai Radio 2 that a new single entitled "B3" would be released in September and a new album is expected to be released in March 2013.
On 14 September 2012, the band announced that they would release a five-track EP titled B3 on 12 October.
The only professional review came from Consequence of Sound. Reviewer Katherine Flynn, after criticising the band's previous album, 2009's Battle for the Sun, which she wrote "didn't feel as urgent, or as true, as anything that had come before [in Placebo's canon]", saw B3 as a "[return] to their loud, largely minor-key hijinks" and writing that the EP "kicks", citing the ending track "Time Is Money" as a highlight.
