I've heard the Barber quartet a dozen times now, most recently last week at Yoshi's SF (she played their 9' Hamburg Steinway), and was once again struck by the consummate musicianship and friendly collaboration that is obvious as they play together. Audiophiles often dig Patricia because many of her recordings are sonically superb, but people, if you have a chance to hear her live, go for it. Her drummer and bass player (Michael Arnopol, who has played with her since the 1980's) are virtuosos on their instruments. I also highly recommend her most recent CD--a tribute to Cole Porter that is just a musical pleasure.
