Constantly refining their sound with an experimental feel and cinematic arrangements, Portland, Oregon’s Grails return to Philadelphia on Sept. 14 at Boots And Saddle and Brooklyn on Sept. 15 at the Saint Vitus bar. This marks Grails’ first U.S. tour in two years. They’ll be supported by Wreckmeister Harmonies and their own side-project Lilacs And Champagne, and will likely have copies on hand of their new collection, Black Tar Prophecies 4, 5 & 6, compiling material from their ongoing series of EP releases. Grails’ last full-length, Deep Politics, was released in 2012.
