Rule of 3 is a 3-piece acoustic band from the North Shore of Boston. Our name comes from the Rule of 3 principle which suggests that when things come in threes, they are inherently more enjoyable and satisfying than other numbers. As a band, we hope that you will find our music & harmonies to be more evidence of this truth. We invite you to come and experience Rule of 3′s take on some of the great harmony songs from the 60’s, 70’s & 80’s!
