Stephanie at Fretless Strings coordinated the string duo for our wedding. The music selection is huge and they just so happened to play our song, "The Luckiest" which we certainly didn't expect! Stephanie was always responsive and worked with me to get our songs chosen. On our wedding day it was raining and because string instruments can't be played outside they played inside and were mic'ed so that we could hear the music they were playing as they sat right inside the doors. I consider this extremely flexible as you never know what weather may be like. We were so pleased! Bottom line: very reliable and easy to work with! And most importantly, beautiful music!
