The legend of The Killers goes like this: Brandon Flowers responded to guitarist Dave Keuning’s classified ad in Las Vegas Weekly. Dave handed Brandon a four-track demo of “Mr. Brightside” and the rest, as they say, is history. Five smash albums and multiple world tours later, Keuning took a break to explore his musical passions outside of his day job. Prismism are songs recorded in his San Diego home studio. Tracks like “Boat Accident” and “Ruptured” reveal Keuning’s love of keyboard-based rock and pop. The songs are intimate, lush with pretty melodies and lyrical origami. “I Ruined You” and “Restless Legs” feel the most Killers-ish, with their guitar attacks and rumbling beats. Meanwhile, “If You Say So,” the acoustic “Gimme Your Heart,” and the vocoder-heavy title track show that behind The Killers’ stadium hits resides a restlessly creative beast.
