The vocal powerhouse that is Jessie J giving a definitive acoustic performance of her biggest single to date in the second of our exclusive series with world famous Red Bull Music… ‘Rehearsal Rooms’, an original series presented by PinBoardBlog.com and filmed by our production house PinBoard Film. Filmed before Christmas and caught live in one take, she gave us a glimpse of the magic windpipes with a dollop of attitude before her biggest gig at London’s XOYO, where later that evening she blew the remaining socks off industry wigs. She’s gone on top both the BBC Sound of 2011 list and win Critics Choice Award at Brit Awards 2011 so she’s at the top of her game and wholly ascending right now (we’ve been praising her register since the humble YouTube era, lol). Jessie J’s debut album Who You Are is out this year whilst her second single drops in March. For now, enjoy this stripped down, swagged out rendition of her massive number ‘Do It Like A Dude’.
