Eleanor Friedberger has a solo disc due out next month called Last Summer, on which the female half of the Fiery Furnaces dials down her main band’s jumpy art-pop mania and emphasizes her laidback singer-songwriter roots instead. You can probably expect Friedberger to preview some of her new material tonight, when she headlines one of the niftier shows of this weekend’s Brooklyn-centric Northside Festival; on the other hand, she and her brother Matthew have made a career out of upending set-list expectations. Friedberger shares the bill with Ida, New York’s long-running emo-folk institution, and Rebecca Gates of the late, great Spinanes, as well as a still unannounced “special secret guest.”
