Solange Knowles` record sales boost after elevator incident

London: Singer Solange Knowles saw a boost in her sales in the US following her notorious elevator fight with brother-in-law Jay Z. Earlier this month, surveillance footage appeared to show the R&B singer lashing out at the rapper as she left a party at The Standard Hotel following New York`s Met Gala with her sister Beyonce and her hip-hop mogul husband, reportedly. The trio has since spoken out about the video, insisting they have "worked through" the drama, and the controversy appears to have boosted Solange`s career - her record sales have increased by 233 per cent. According to Nielsen SoundScan data for the week ending May 18, the `Losing You` singer`s digital sales were at 2,000 downloads, up from 600 the previous week. Solange`s last release was her 2012 Ep, titled True.
