Alice Glass may dispense with the audience chit chat you might find with other artists; for her and her bandmate Ethan Kath and their gigs as Crystal Castles, it certainly doesn’t make them any less interactive… with a reputation for high energy shows, she spent a good portion of the concert diving into the audience and literally surfing the crowd at the Showbox SoDo in Seattle last night. The Canadian duo, along with drummer Christopher Chartrand, rocked their unique and experimental lo-fi electronic synthpop/synthpunk sound with synthesizers including an Atari 5200-chip modded keyboard. Their live act is definitely worth checking out, as the somewhat chaotic staging and delivery is somewhat in contrast with the electronic music, fusing raw energy with 8-bit retro sounds to bring something to life that felt and looked like raw rock and roll, but sounded like something altogether new and different.
