What the OP should read is that Lana Del Rey is the first artist in 14 years to perform on SNL before releasing an album at all. Her first physical album is out at the end of the month; she put out a digital EP a few months ago. Impressive considering SNL is pretty huge for any artist, but less so when you consider the money behind her and who her supporters are.
She's the definition of a manufactured talent; stage name chosen by the label, promoted by billionaire daddy, and hyped by every blog and magazine that they could buy. Nobody will know who she is in a year.
