The Everley Brothers, Simon and Garfunkle, Chad Mitchell Trio, The Beach Boys and probably several more that will come to mind once I post this.

This isn't really folk, but I loved Wilson Philips--their harmonies were so tight!

I love to harmonize and started off at a very young age with my dad and my sister. For years they were the only 2 people I could sing with because everytime I'd try to harmonize with someone else, that person would inadvertantly leave the melody and copy me. Then I joined a folk/world music a capella choir and I finally found my home. Here was a group of people who I could harmonize with to my heart's content! I also do some arranging for that choir; creating/writing harmonies is my true passion. To me, there is nothing that compares to the sound of 3,4,5,6,or 7-part harmony.

Does anyone else here gets goosebumps whenever you hear that perfect blend of harmonies?
