Based on some twitter posts earlier in the week about a “big announcement,” rumors were circulating that The Killers hiatus was actually a break up. As it turns out, the big announcement was confirmation of a suspected solo album by Killers front man Brandon Flowers, which will be titled Flamingo.After a week of Web teases, Flowers announced that he’d be stepping out on the band with a disc called Flamingo, which the band’s official Web site says is “coming soon.” The announcement, in the form of a broken-down neon sign that has the singer’s name and a playing-card club lit up in red, is accompanied by a spare electronic track made up of pinging synth notes and some wordless falsetto vocals. A spokesperson for the group could not be reached for further details about the album’s release.It appears Flowers isn’t the only Killer taking a break, as drummer Ronnie Vannucci has signed up to perform in a supergroup called Mt. Desolation, featuring members of Keane, Mumford & Sons, Noah and the Whale and the Long Winters
