Guitarist and songwriter Trevor Hall has had an interesting journey. Born and raised in South Carolina, he learned the traditions of blues as a child. Then, he moved to Los Angeles and studied classical guitar. There he discovered yoga and Eastern spiritualism, all of which informs his output of acoustic rock, reggae and soul music.
