Folk music has evolved over the past few years, particularly with the emergence of the indie scene, but it’s refreshing to find a band keeps to it’s roots. Seattle’s King Friday occasionally features a piano in their songs, but that’s as far as they stray in terms of instrumentation from their straightforward acoustic guitar fueled folk pop. Joe Bolton, Matthew Sweeney, and Alex Folkerth use this simplicity of sound to showcase their engaging lyrics, vocal dynamics, and harmonization. Their three albums, including their latest “Let Him at Cake (Songs for Birds)” are available for download here.-Lucy Sherman
