When Franz Ferdinand announced their intention to make a pop record, it was a bit of a head-scratcher. The Scottish foursome -- purveyors of catchy, danceable rock tracks like Take Me Out and Do You Want To -- werent exactly trafficking in Austrian chamber music before. And what to make of the bands aborted recording session with Sugababes producer Brian Higgins? What exactly did they mean by pop? Were they dipping into Lady GaGas face paint? This is dirty pop, clarifies lead singer Alex Kapranos. My favorite music has always been that: direct pop melodies, but this dirty rawness at the same time. Not the worst starting point, and the result, Tonight: Franz Ferdinand, is a fans relief, the equivalent of being summoned to a 1 a.m. after-party by a reliably engaging friend. Influenced by classic disco, Grace Joness Nightclubbing, and the 80s art-punk label 99 Records, it evolved into a concept album about nightlife. Turn It On and What She Came For offer a bit more groove and swing than usual, and Lucid Dreams is an eight-minute synthesizer track that dissolves into Detroit house. We were really into the idea of dance music that is near your heartbeat, like 104 beats per minute, says Kapranos. Thats when you feel like youre hypnotized, when you lose yourself. Theres a real heaviness and power to that tempo. American urban stuff is like that, but British bands tend to be too fidgety and fast. The group recorded Tonight in a 19th-century Glasgow municipal building last occupied by a drug rehab. Because of complaints about the noise from a nearby school for the deaf (ironically enough, says Kapranos), they boarded up the windows with Sheetrock, creating a perpetual midnight. Then they acquired some low-tech backup assistance when Kapranos and guitarist Nick McCarthy found a box of skeletons outside a doctors office and brought it into the studio. We were looking for some dry percussion sounds, Kapranos explains. So we rattled a jar with teeth in it. These are tiny sounds you cant replicate with Pro Tools. The band has taken an unconventional approach before, most notably with Michael, a track from their 2004 debut that depicted a sweaty same-sex clinch in a club. The song was considered coolly provocative, and Kapranoss breathless delivery intensely homoerotic. In a year that wasnt short on guys making dance music with guitars, the songs thematic Bowieness set Franz Ferdinand apart from their contemporaries. I find it kind of odd there was quite a big fuss made over that song, says Kapranos. We didnt think of it as anything out of the ordinary. We were at a club the night before, and a friend of mine, who is normally straight, went off with a guy. I thought, Cool, lets write about that. I was putting myself into other peoples characters to expose their emotions. That happens on the new album also. The storytelling, that is, not the sexual ambiguity: Were straight guys for the most part, so it might seem a little contrived if we were to repeat that again, says Kapranos, laughing. But Tonight was inspired by the bands longtime hangout, Optimo, a Glasgow club where sexual and musical pluralism is the norm. The point of Michael was that definitions sometimes dont matter, explains Kapranos. Thats what it always seemed like in the clubs we hung out in. There wasnt a gay-straight divide. It just seemed like a blur to me. I much prefer socializing that way. On Election Night, Kapranos stayed up until 5 a.m. U.K. time to watch Barack Obamas victory speech. It was wonderful to hear Obama say it doesnt matter if youre black or white, and then gay or straight as well, he says. It was a magnificent speech, like listening to something by Roosevelt or Winston Churchill. But Kapranos, who has a married gay friend in London, was troubled by that nights legislative setbacks. It is kind of terrifying that gay marriage would be outlawed, he says. That you would want to remove that choice from a major part of society is disturbing. Before setting off on a world tour, the singer is finalizing the albums artwork, in which Franz Ferdinand ditch their trademark constructivism for snapshots inspired by Cindy Shermans imaginary films and the crime scene photography of Weegee. But despite Tonights more elaborate visual style, Kapranos remains committed to the simple pleasures of the dance floor. Ill always be a big fan of pop, he says. Youre allowed to be that in America, more than in the U.K. There, the idea is that if youre indie, you cant be pop. I think thats bollocks.
