Buzzy Lee is the mask behind which Sasha Spielberg hides. Yes, those Spielbergs. Her dad is Steven Spielberg, and now the cat’s out of the bag. But Sasha has spent all her career running away from the privileges associated with that surname and has never put it out there. That’s why she set up a weird-folk band with her brother Theo in 2010 and called it Wardell, rather than Spielberg Sons & Daughters. For the same reason, also, she later got together with her high school friend Nicolas Jaar and started the indietronic duo Just Friends. Now, in the same spirit of discretion and self-assertion, she is debuting solo under another alias (although she is still with Jaar, this time as a producer) with a selection of fragile tracks that float as gracefully and beautifully as water lilies do. Bedroom electronic music that is knocking on the door of the room that Julia Holter used to occupy.
