Bonne Finken’s remarkably versatile voice allows her to transcend genres effortlessly. One moment, the Iowan is melting your heart with a classic soul-inspired ballad. The next, she’s making your heart race with a take-no-prisoners approach to a slice of driving, R&B-tinged pop. Finken even has the capability to carry a down-and-dirty, loud rocker. Her 2011 “Expectation Fall” EP pairs this adaptability with an adventurousness that results in a refreshing and exhilarating musical experience — punctuated with Finken’s phenomenal lead vocal performance.
