Sometime just after the midpoint of Madeleine Peyroux’s performance Sunday at the Berklee Performance Center, something strange happened: People started leaving. It wasn’t a mass exodus, probably just a dozen or so, but they got out of their seats a few at a time and didn’t return. Two or three times as many did the same before the encore. Maybe they simply decided that Peyroux wasn’t worth hearing anymore.
That wasn’t the majority opinion - the remaining audience’s applause was enthusiastic - but there were times when it wasn’t hard to sympathize. Thanks in part to the timbre of her voice, Peyroux has received plenty of Billie Holiday comparisons over the past 13 years. But Sunday’s performance showcased little more than a few borrowed affectations, like the way she’d slide in her upper register from one note to something approximating the next or start words with a quick dip up or down.
