The reclusive quartet known as androp make music in the space where fizzy electronic elements intersect with shout-along rock. Formed in the late ‘00s, the group quickly climbed the rungs of the Japanese music scene with driving guitar supported by a flurry of synthesizers. Whether letting light-speed keyboard guide the way or boosting fidgety guitar-and-drum tracks with squiggly noise, androp is plugged into an apparently endless supply of energy. As often as not, this translates into slow-building numbers and big choruses that shine with equal brilliance in the arena or the club.
