"The Brass Tacks recording, with ten compositions and arrangements by its leader, is one of the most pleasant surprises to appear in Brazil in the area of jazz during recent years."
Jornal do Brasil
"The band is daring in its repertoire, playing all original tunes written and arranged by Ms. Duncan. It's so difficult to hold an audience's attention with the program made up totally of unfamiliar tunes that most leaders don't take the risk. Duncan does -- and succeeds."
The Christian Science Monitor
"Duncan, a small woman whose hands can barely stretch an octave ... is a cooking, inventive pianist."
"It's quite a refreshing sound, not only because of the brass, but also the hip compositions and strong soloists. My only complaint is that I didn't hear it sooner."
The Doobie Brothers
"Duncan is primarily a pianist and composer who has concentrated on writing for brass players and finding good
ones to play her glimmering, robust music."
