When four female singers gathered in New York in 1986 for informal readings of a cappella Medieval chant, little could they have envisioned a three-decade career brimming with countless performances around the globe and 20 recordings with 20 million copies sold.
An impressively large crowd gathered to hear Anonymous 4 Sunday in Hyde Park, grateful to be chosen as the locale for their last local touring date, in the University of Chicago Presents series.
No doubt many of their devoted fans in the gargantuan Rockefeller Chapel hoped that the quartet would reconsider its decision to disband. But with other projects in the pipeline for each member, it appears that the end has indeed come, even if a similar and ultimately premature pronouncement was made in 2004. If the near-perfection of their vocal purity has frayed a bit since their early days, they easily held listeners in rapt attention throughout the 70-minute program.
