Serebro are looking and sounding like a group with a great deal of experience behind them after a funkier rehearsal than ever today.

The team is taking Eurovision very seriously, and the first run through was marked by the melody being played along with the singers by a harsh synthesiser sound, presumably as a pitch perfecting exercise.

Sexy, sassy
In sexy black outfits, the girls strut their stuff through three minutes of sassy, mainstream pop rock with a performance straight from a chart-busting tour. The cameras really make the most of them with fast zooms, edgy, rotating pans and nice close-ups. Bright rings of white light burst on behind them for the dance break, knocking them into near silhouette; the effect is stunningly dramatic and the girls move almost robotically in time.

The red cross-hatch design still moves behind the group, switching to the mega-cool Matrix style blue background for the bridge.

The girls responded happily to the crowd reaction, jumping and clapping themselves with delight at the applause. Russia looks cooler and cooler with each rehearsal; clearly going for the chart hit votes, they look to convince a fair few people if the rehearsal performance is anything to go by.
