Perfect Fifths performed at my wedding & were AMAZING! They even played instruments & arranged all ceremony music. Perfect Fifths sang during cocktail hour & led our first dance "For the Longest Time" by Billy Joel. And they encouraged our guests to sing along too--it was so beautiful. I researched many acapella groups & Perfect Fifths were the most reasonable & modern. They know what audiences want to hear & the members have fun while performing. Most importantly, the group sings BEAUTIFULLY!!! This is 100% honest feedback. I don't know the group personally. Feel free to contact me if you want a reference. I strongly believe the Perfect Fifths are wonderful artists.
