David is a consummate professional, and the groups he hires out are fantastic. We contracted both the string duo for our wedding(who were willing to stand out in the blazing sun AND go talk to the guy playing trombone just outside the square and get him to stop for the ceremony) and the jazz quartet for our reception(who were FANTASTICALLY good – they played every weird selection we threw at them, and even picked up on the ad hoc eastern European number my mother in law started up on the dance floor), and we did so in a horribly unprofessional, last-second frenzy of phone calls. David was very helpful despite our eleventh hour insanity, and was even willing to send the duo out without having received our second contract. He contracts some really excellent musicians(email me if you want to hear about the quartet that played our reception – seriously fantastic group), and was prompt and responsive to our every question.
