It’s only appropriate that Roan would forever alter the Tiny Desk. Because, at the risk of sounding hyperbolic, this is a stunning set: Performing five songs from Midwest Princess, Roan worked through songs of youthful heartache (“Casual”), queer liberation (“Pink Pony Club”), mournful alienation (“California”) and two decidedly different forms of chaotic seduction (“Picture You,” “Red Wine Supernova”). In every mood and every song, she’s utterly commanding — witty and whip-smart, vocally assured and charismatic beyond words.
