This was a quartet but they agreed to a duo for our ceremony and cocktail hour. Beautiful music; violin and viola. They provided a demo CD. I originally found them on www.gigmaster.com so did not have a referrel so the CD and online reviews in gigmaster was of great help. We were very pleased and since our ceremony was outdoors in the sun we did provide extra chairs and market umbrella for them to sit under. I highly recommend this group, they beat the lowest bid I had as well. 714.572.1755
