A friend, who is a singer/songwriter/acoustic guitar player, is recording a CD of his songs. He is a really good lyricist and songwriter but his songs all sound the same, in about the same key (G) and with the same acoustic guitar strum pattern. All of his songs sound the same and kind of bland. He and his brother are recording it at home not in a studio. He really needs a producer to help give him ideas about adding instruments and arrangements. So I can't decide if I should give him recommendations, play on the CD or bow out of the project. What would you do?
