The National has been around for more than a decade—a lifetime by indie buzzband standards—but it continues to put out solid records. The Brooklyn-based quintet’s latest, 2010’s High Violet, proves that the band is still relevant, and at the top of its game. The album features collaborations with Bon Iver’s Justin Vernon and Sufjan Stevens; it’s a more polished, lavish rendition of The National’s particular brand of alt rock. Philadelphia is in for a special stop on the band’s fall tour: It will perform not one but two shows, both of which are with Yo La Tengo and Wye Oak. The National performs with Yo La Tengo and Wye Oak at 7 p.m. Wednesday, September 7th, and Thurday, September 8th, at the Academy Of Music; tickets to the all-ages shows are $39.50.
