I don't often (read, almost never) get around to posting my Inquirer concert reviews — sometimes because thanks to the paper's nightmarish website, I can't even find the damn things — but I'm pretty happy with how this account of Leslie Feist's show at the Academy of Music turned out. For me, at least, the show was a revelation, a dramatic and at times emotionally violent performance that sent me back to Feist's albums, wondering, "How did I miss that?" In all honesty, I still thought of her principally as the woman behind the ubiquitous, Muppet-friendly "1234," pointedly absent from Tuesday's two-hour show. But I also think that she's got an unfortunate tendency to sand the edges off her spiky and surprising songs on record; they literally get lost in the mix. The show transformed how I think of her, a rare experience for which I'm always grateful. Plus, any chance to drop a gratuitous Mary Margaret O'Hara in the pages of a major daily is a welcome thing.
