What would Joni Mitchell sound like covering Nick Drake with Bon Iver’s banjo player and percussionist? Whatever that is, Buenos Aires’ Karina Vismara would smoke ’em. She has a voice, and it’s never caught trying to justify boring guitar playing or any old trick we’ve heard a million times. Vismara’s secret weapon is in her writing, for she knows when to move from haunting coffee-shop fingerpicking folkie to I’m Gonna Bang And Wail On My Guitar And Scream Without Raising My Voice And I Will Devour The Pin That You Can Hear Drop When I Play. She’s that good.
