Rich, sweet harmonies drip off Band of Horses like maple sap on a warm spring morning. The bearded band from Carolina hitches all kinds of suffixes to the tight singing on their soaring third album, "Infinite Arms": country-indie-pop, country-grunge, country-shoegaze, country-maudlin-ballads. During their solid set opening for Pearl Jam at Nationwide Arena in May, it was more like country-jam-band, as they calmly noodled in front of a Pink Floyd-style projection screen (country-psychedelia?).

There's another Pearl Jam connection on this visit. Opening for Band of Horses is Brad, the side project of PJ's Stone Gossard. Trippy singer/songwriter Blake Mills will be there, too.
