Yes Ms Lana Del Rey, you stay stuck to that piano, because its where you give your best performances!
Singing Without You from her debut album, Born To Die [Review], Lana showed the world she is a human being after all, giving a warmth and humility often missing from her performances. Perhaps it was due to her clearly being surrounded by fans, but Lana looked almost comfortable on stage and her surroundings, and this showed in her voice.
Displaying a raft of different timbres and parts to her range, she sang the love song gorgeously, and in a way that deviated from the softer, Betty-Boop-like delivery of the album. It was a stark contrast to her robotic, and much ridiculed, Saturday Night Live performance [here], or her spot closing Jonathan Ross' chat show [here].
If Lana Del Rey can just get her technique to match her ability to communicate the lyrics of the song she would be unstoppable as a vocalist. However, there is definitely growth happening in the star's live voice as she gets used to her place in the limelight, so perhaps it won't be too long now.
