Millbrook’s Serena Ryder made waves with her 2006 collection of covers If Your Memory Serves You Well. The record showcased the then-22-year-old’s formidable vocal talents and her abilities as an arranger, but was dragged down by three of her own creations. The 13 self-penned songs on Is It OK are vast improvements, but Ryder has yet to find the song to elevate her above the teeming hordes of female folk-rockers. “Little Bit of Red” showcases a distinctive voice that inexplicably mixes Alanis Morissette’s shrill highs and Amanda Marshall’s raspy lows. But too many songs here employ typical love-and-loss lyrical tropes. Ryder has the pipes. Now she just needs to find her voice.
