Noah Gundersen released his third album, "White Noise," last September. It marks a shift in the Seattle singer-songwriter's folk music. Gundersen brings in a backing band on several songs to give the record a fuller, uplifting rock sound -- though he includes some plaintive piano ballads as well. Gundersen visited the CPR Performance Studio accompanied by his sister Abby on violin. He played stripped-down versions of two songs from "White Noise" along with a new B-side. He also spoke with Jeremy Petersen about the decision to retool his sound, reconnecting with his siblings by playing music together and learning to embrace his early musical output.
