San Francisco-based singer/songwriter Matt Nathanson's "Come On Get Higher," from sixth studio album "Some Mad Hope," is his biggest hit to date—an adult top 40 smash and his first to chart on the Billboard Hot 100. Along with the magical strum of his acoustic guitar, there's a soft optimism in Nathanson's raspy voice, with a bridge that spans whispering falsetto and soulful belting. Much of his burgeoning success may owe thanks to spending a good portion of the year on the road, first touring with Lifehouse and last fall headlining with Jessie Baylin. "Come On Get Higher" sounds like a bold new beginning for Nathanson. —Michael Menachem
