I'd suggest some of your existing members learn to sing harmony. It's pretty easy once you learn how to. my band is a rock band, but we do alice in chains style harmony, and three of the four members sing, so there's a lot of room for it. the biggest mistakes people make early on in trying to sing harmony is singing octaves. this rarely works. most of the time, 3rds 4ths and 5ths work best. i'd say 99.9 percent of our harmonies are 3rds and 4ths. if youre interested in that sort of thing, contact me.
