Neo-Traditional Country Music Trio The Castellows Are Bringing A Literal Meaning To The Phrase “family Tradition.” The Band Comprised Of Sisters Ellie Lead Guitar Powell Banjo And Lily Vocals Hail From Small Rural Georgetown Georgia But Now Call Nashville Home. The Castellows’ Sound Is Traditional Yet Modern. Authentic Yet Harnessed. The Common Thread Among The Trio Other Than Their DNA Is Their Masterful Three-Part Harmonies Which Blend Together To Create One Singular Almost Angelic Voice.
