London synth-pop duo La Roux-consisting of frontwoman Elly Jackson and producer Ben Langmaid-has been posting gains on Billboard's charts in recent weeks, thanks to its single, "Bulletproof." The perky number is bulleted at No. 29 on the Mainstream Top 40 radio airplay chart, rises 35-29 on Hot Digital Songs and gives the act its first top 40 hit on the Billboard Hot 100, as it climbs 48-36.
Initially a hit in the United Kingdom, where it debuted atop the Official Charts Co.'s singles list in June 2009, the Big Life/Polydor/Cherrytree/Interscope song first reached a U.S. Billboard chart Aug. 1, 2009, when it bowed at No. 38 on Hot Dance Club Songs. It ultimately hit No. 1 in September but didn't cross over to Mainstream Top 40 until this year, when it entered the March 20 chart at No. 37. Since then, thanks to the act's radio support, touring and TV appearances (including "The Ellen DeGeneres Show" and "Last Call With Carson Daly"), both "Bulletproof" and the act's self-titled album have seen steady sales gains.
"Bulletproof" has shifted 406,000 digital downloads, according to Nielsen SoundScan, while its album has sold 47,000. This week, the latter notches its best sales week yet, with 3,000 (up 34%). It re-enters the Billboard 200 at No. 187 and climbs to a new peak on Top Heatseekers Albums at No. 6.
