One voice is all it takes. The right vocalist can make you fall in love at first listen, elicit tears, or bring you back to a different era altogether. A microphone and a stage remain the only necessities. That holds true for New York-based singer and songwriter Morgan James. On her full-length debut for Epic Records titled “Hunter,” she casts an unbreakable spell with a powerhouse voice equally inspired by smoky soul, swaggering R&B, theatrical swing, and a virtuosic classical poise. Her latest studio album is her first as an independent artist, and “Reckless Abandon” is her most personal outing yet, prompting the Huffington Post to call her the “Brightest Breakout Artist of the Year.”
