The Gift Machine's "Hard Facts are Still Uncertain", is a strong folk album with mulitple catchy songs. They have been around since 1999, changing members and sounds throughout the past 15 years, and you can tell from the sound of their album that they know what they are doing, and enjoy the music they make. The first song on the album, Dark Waters, is a great start to an album, and definetly a song to play on the air if you want airy-folk that makes you want to go on a road trip. Definetly take a listen to this album.
Sufjan Stevens (but with more guitar, and more folk)
