With 'Femme Fatale Vol. 2,' Mon Laferte shows she's at her musical peak

"Femme Fatale Vol. 2" is a panoramic double album that simmers with ambition.

Anchored on a near-orchestral soundstage, its 20 tracks ricochet from in-your-face punk dissonance to majestic broken-heart dirges, a lovely duet with St. Vincent, rootsy folk interludes and farfisa-rich lounge.
