KCRW’s World Festival has put together a must-see trifecta for this Hollywood Bowl show. Slavic revivalists Devotchka are sure to wow with songs that vary from rollicking gypsy pop to those seemingly composed for Little Miss Sunshine 2. Sharing the bill are Rodrigo y Gabriela, the Mexican duo famed for their incredible acoustic guitar shredding skills. They defy categorization, but if pressed you might settle on heavy-metal flamenco. Lord Huron, a very buzzy LA folk-pop band, will open the show with gorgeous harmonies that draw comparisons to Local Natives.
