Solange Knowles has struggled for years to step out of the shadow of her older sister, Beyoncé. Now freed from a major label, True confirms that, yes, she's sort of a hipster. Her songs, co-produced with Lightspeed Champion, drip fashionably with '80s pop and synths. Yet she has a knack for lyrical whimsy. On "Don't Let Me Down," she sings, "I can't get up/ I moved the mountains in my mind." She twists the phrase "played around with your heart" on "Lovers in the Parking Lot" with poetic ease. She's on the cusp of an artistic breakthrough, if she can only figure out how to get there.
